Upon receipt of such notice from the Borrower, the Administrative Agent shall promptly notify each Lender by telephone or telecopy of the contents thereof.

(ii) Conversions. The Borrower may, without regard to the applicable Payment Date and upon at least three (3) Business Days’ irrevocable prior telephonic notice followed by a Request for Advance, Convert all or a portion of the principal of a Base Rate Advance to a LIBOR Advance. On the date indicated by the Borrower, such Base Rate Advance shall be so Converted. The failure to give timely notice hereunder with respect to the Payment Date of any Base Rate Advance shall be considered a request for a Base Rate Advance.

(c) LIBOR Advances. Upon request, the Administrative Agent, whose determination in absence of manifest error shall be conclusive, shall determine the available LIBOR Bases and shall notify the Borrower of such LIBOR Bases to apply for the applicable LIBOR Advance.

(i) Advances. The Borrower shall give the Administrative Agent in the case of LIBOR Advances at least three (3) Business Days’ irrevocable prior telephonic notice followed immediately by a Request for Advance; provided, however, that the Borrower’s failure to confirm any telephonic notice with a Request for Advance shall not invalidate any notice so given if acted upon by the Administrative Agent. Upon receipt of such notice from the Borrower, the Administrative Agent shall promptly notify each Lender by telephone or telecopy of the contents thereof.

(ii) Conversions and Continuations. At least three (3) Business Days prior to the Payment Date for each LIBOR Advance, the Borrower shall give the Administrative Agent telephonic notice followed by written notice specifying whether all or a portion of such LIBOR Advance (A) is to be Continued in whole or in part as one or more LIBOR Advances, (B) is to be Converted in whole or in part to a Base Rate Advance, or (C) is to be repaid. The failure to give such notice shall preclude the Borrower from Continuing such Advance as a LIBOR Advance on its Payment Date and shall be considered a request to Convert such Advance to a Base Rate Advance. Upon such Payment Date such LIBOR Advance will, subject to the provisions hereof, be so Continued, Converted or repaid, as applicable.

(d) Notification of Lenders. Upon receipt of irrevocable prior telephonic notice in accordance with Section 2.2(b) or (c) hereof or a Request for Advance, or a notice of Conversion or Continuation from the Borrower with respect to any outstanding Advance prior to the Payment Date for such Advance, the Administrative Agent shall promptly but no later than the close of business on the day of such notice notify each Lender having the

-21-

applicable Commitment by telephone, followed promptly by written notice or telecopy, of the contents thereof and the amount of such Lender’s portion of the Advance. Each Lender having the applicable Commitment shall, not later than 12:00 noon (New York, New York time) on the date of borrowing specified in such notice, make available to the Administrative Agent at the Administrative Agent’s Office, or at such account as the Administrative Agent shall designate, the amount of its portion of any Advance that represents an additional borrowing hereunder in immediately available funds.

(e) Disbursement.

(i) Prior to 2:00 p.m. (New York, New York time) on the date of an Advance hereunder, the Administrative Agent shall, subject to the satisfaction of the conditions set forth in Article 3 hereof, disburse the amounts made available to the Administrative Agent by the Lenders in like funds by (A) transferring the amounts so made available by wire transfer pursuant to the Borrower’s instructions, or (B) in the absence of such instructions, crediting the amounts so made available to the account of the Borrower maintained with the Administrative Agent.

(ii) Unless the Administrative Agent shall have received notice from a Lender having an applicable Commitment prior to 12:00 noon (New York, New York time) on the date of any Advance that such Lender will not make available to the Administrative Agent such Lender’s ratable portion of such Advance, the Administrative Agent may assume that such Lender has made or will make such portion available to the Administrative Agent on the date of such Advance and the Administrative Agent may in its sole discretion and in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent an applicable Lender does not make such ratable portion available to the Administrative Agent, such Lender agrees to repay to the Administrative Agent on demand such corresponding amount together with interest thereon, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Administrative Agent, at the Federal Funds Rate.

(iii) If such Lender shall repay to the Administrative Agent such corresponding amount, such amount so repaid shall constitute such Lender’s portion of the applicable Advance for purposes of this Agreement. If such Lender does not repay such corresponding amount immediately upon the Administrative Agent’s demand therefor, the Administrative Agent shall notify the Borrower, and the Borrower shall immediately pay such corresponding amount to the Administrative Agent, with interest at the Federal Funds Rate. The failure of any Lender to fund its portion of any Advance shall not relieve any other Lender of its obligation, if any, hereunder to fund its respective portion of the Advance on the date of such borrowing, but no Lender shall be responsible for any such failure of any other Lender.

(iv) In the event that, at any time when there is no Default and each of the conditions in Section 3.2 hereof has been satisfied, a Lender having an applicable Commitment for any reason fails or refuses to fund its portion of an Advance and such failure shall continue for a period in excess of thirty (30) days, then, until such time as such Lender has funded its portion of such Advance (which late funding shall not absolve such Lender from any liability it may have to the Borrower), or all other Lenders

-22-

have received payment in full from the Borrower (whether by repayment or prepayment) or otherwise of the principal and interest due in respect of such Advance, such non-funding Lender shall not have the right (A) to vote regarding any issue on which voting is required or advisable under this Agreement or any other Loan Document, and such Lender’s portion of the applicable Loans and Commitments shall not be counted as outstanding for purposes of determining “Majority Lenders” hereunder, and (B) to receive payments of principal, interest or fees from the Borrower, the Administrative Agent or the other Lenders in respect of its portion of the applicable Loans until all applicable Loans of the other Lenders have been fully paid.

Section 2.3 Interest.

(a) On Base Rate Advances. Interest on each Base Rate Advance shall be computed on the basis of a year of 365/366 days for the actual number of days elapsed and shall be payable at the Base Rate Basis for such Advance, in arrears on the applicable Payment Date. Interest on Base Rate Advances then outstanding shall also be due and payable on the Maturity Date.

(b) On LIBOR Advances. Interest on each LIBOR Advance shall be computed on the basis of a 360-day year for the actual number of days elapsed and shall be payable at the LIBOR Basis for such Advance, in arrears on the applicable Payment Date, and, in addition, if the Interest Period for a LIBOR Advance exceeds three (3) months, interest on such LIBOR Advance shall also be due and payable in arrears on every three (3) month anniversary of the beginning of such Interest Period. Interest on LIBOR Advances then outstanding shall also be due and payable on the Maturity Date.

(c) Interest if No Notice of Selection of Interest Rate Basis. If the Borrower fails to give the Administrative Agent timely notice of its selection of a LIBOR Basis, or if for any reason a determination of a LIBOR Basis for any Advance is not timely concluded, the Base Rate Basis shall apply to such Advance.

(d) Interest Upon Event of Default. Immediately upon the occurrence of an Event of Default hereunder, the outstanding principal balance of the Loans shall bear interest at the Default Rate. Such interest shall be payable on demand by the Majority Lenders and shall accrue until the earlier of (i) waiver or cure of the applicable Event of Default, (ii) agreement by the Majority Lenders (or, if applicable to the underlying Event of Default, the Lenders) to rescind the charging of interest at the Default Rate or (iii) payment in full of the Obligations.

(e) LIBOR Contracts. At no time may the number of outstanding LIBOR Advances with respect to any tranche hereunder exceed four (4).

Changes to the Applicable Margin shall be effective as of the second (2nd) Business Day after the day on which the Debt Rating changes. Any change to any Debt Rating established by Standard and Poor’s, Xxxxx’x or Fitch shall be effective as of the date on which such change is first announced publicly by the applicable rating agency making such change and on and after that day the changed Debt Rating shall be the Debt Rating of such rating agency for purposes of this Agreement. If none of Standard and Poor’s, Xxxxx’x or Fitch shall have in effect a Debt Rating, the Applicable Margin shall be set in accordance with part F of the table set forth in Section 2.3(f)(i). If Standard and Poor’s, Xxxxx’x or Fitch shall change the basis on which ratings are established, each reference to the Debt Rating announced by Standard and Poor’s, Xxxxx’x or Fitch, as the case may be, shall refer to the then equivalent rating by Standard and Poor’s, Xxxxx’x or Fitch, as the case may be.

Section 2.4 Commitment and Letter of Credit Fees.

(a) Commitment Fees.

(i) The Borrower agrees to pay to the Administrative Agent for the account of each of the Lenders having (i) a Revolving Loan Commitment in accordance with such Lender’s applicable Commitment Ratio, a commitment fee on the unused Revolving Loan Commitment of such Lender for each day from the Agreement Date through and including the Maturity Date and (ii) a DDTL Commitment in accordance with such Lender’s applicable Commitment Ratio, a commitment fee on the unused DDTL Commitment of such Lender for each day from the Agreement Date through and including the DDTL Commitment Termination Date, in each case, at the applicable rate set forth below, based upon the Applicable Debt Rating (as such Applicable Debt Rating is determined pursuant to Section 2.4(a)(ii)) in effect on such date as set forth below:

Such commitment fee shall be computed on the basis of a year of 365/366 days for the actual number of days elapsed, shall be payable quarterly in arrears on the last day of each fiscal quarter (provided, that if such day is not a Business Day, such commitment fee shall be payable on the next succeeding Business Day), and shall be fully earned when due and non-refundable when paid. A final payment of any commitment fee then payable with respect to (A) the Revolving Loan Commitments shall be due and payable on the Maturity Date and (B) the DDTL Commitments shall also be due and payable on the DDTL Commitment Termination Date.

(ii) Changes in Commitment Fee; Determination of Debt Rating. Changes to the Commitment Fee shall be effective as of the second (2nd) Business Day after the day on which the Debt Rating changes. Any change to any Debt Rating established by Standard and Poor’s, Xxxxx’x or Fitch shall be effective as of the date on which such change is first announced publicly by the applicable rating agency making such change and on and after that day the changed Debt Rating for such rating agency shall be the Debt Rating of such rating agency for purposes of this Agreement. If none of Standard and Poor’s, Xxxxx’x or Fitch shall have in effect a Debt Rating, the Commitment Fee shall be set in accordance with part F of the table set forth in Section 2.4(a)(i). If Standard and Poor’s, Xxxxx’x or Fitch shall change the basis on which ratings are established, each reference to the Debt Rating announced by Standard and Poor’s, Xxxxx’x or Fitch, as the case may be, shall refer to the then equivalent rating by Standard and Poor’s, Xxxxx’x or Fitch, as the case may be.

(b) Letter of Credit Fees.

(i) The Borrower agrees to pay to the Issuing Bank a fee on the stated amount (reduced by the amount of any draws) of any outstanding Letters of Credit from the date of issuance through and including the expiration date of each such Letter of Credit at a rate of one eighth of one percent (0.125%) per annum, which fee shall be computed on the basis of a year of 365/366 days for the actual number of days elapsed, shall be payable quarterly in arrears on the last day of each fiscal quarter commencing on December 31, 2005 (provided, that if such day is not a Business Day, such Letter of Credit fee shall be payable on the next succeeding Business Day), and shall be fully earned when due and non-refundable when paid.

-25-

respective Commitment Ratios for the Revolving Loans (and the Administrative Agent shall promptly pay to the Lenders having a Revolving Loan Commitment), a fee on the stated amount (reduced by the amount of any draws) of any outstanding Letters of Credit for each day from the date of issuance thereof through the expiration date for each such Letter of Credit at a rate equal to the Applicable Margin for LIBOR Advances under the Revolving Loan Commitments. Such Letter of Credit fee shall be computed on the basis of a year of 365/366 days for the actual number of days elapsed, shall be payable quarterly in arrears for each quarter on the last Business Day of each fiscal quarter commencing on December 31, 2005, and shall be fully earned when due and non-refundable when paid. The Letter of Credit fee set forth in this Section 2.4(b)(ii) shall be subject to increase and decrease on the dates and in the amounts set forth in Section 2.3(f)(i) hereof in the same manner as the adjustment of the Applicable Margin with respect to LIBOR Advances upon satisfaction of the requirements set forth in Section 2.3(f)(i) hereof.

Section 2.5 Voluntary Commitment Reductions. The Borrower shall have the right, at any time and from time to time after the Agreement Date and prior to the Maturity Date, upon at least three (3) Business Days’ prior written notice to the Administrative Agent, without premium or penalty, to cancel or reduce permanently all or a portion of the Revolving Loan Commitments, the DDTL Commitments or, if applicable, the Incremental Facility Commitments; provided, however, that any such partial reduction shall be made in an amount not less than $5,000,000.00 and in an integral multiple of $1,000,000.00. As of the date of cancellation or reduction set forth in such notice, the Revolving Loan Commitments, the DDTL Commitments or, if applicable, the Incremental Facility Commitments, shall be permanently reduced to the amount stated in such notice for all purposes herein, and the Borrower shall pay to the Administrative Agent for the applicable Lenders the amount necessary to reduce the principal amount of the Revolving Loans, the DDT Loans or, if applicable, the Incremental Facility Loans, then outstanding under the Revolving Loan Commitments, the DDTL Commitments or, if applicable, the Incremental Facility Commitments, to not more than the amount of Revolving Loan Commitments, the DDTL Commitments or, if applicable, the Incremental Facility Commitments, respectively, as so reduced, together with accrued interest on the amount so prepaid and any commitment fees accrued through the date of the reduction with respect to the amount reduced.

Section 2.6 Prepayments and Repayments.

(a) Prepayment. The principal amount of any Base Rate Advance may be prepaid in full or ratably in part at any time, without premium or penalty and without regard to the Payment Date for such Advance. The principal amount of any LIBOR Advance may be prepaid in full or ratably in part upon three (3) Business Days’ prior written notice, or telephonic notice followed immediately by written notice, to the Administrative Agent, without premium or penalty; provided, however, that, to the extent prepaid prior to the applicable Payment Date for such LIBOR Advance, the Borrower shall reimburse the applicable Lenders, on the earlier of demand by the applicable Lender or the Maturity Date, for any loss or out-of-pocket expense incurred by any such Lender in connection with such prepayment, as set forth in Section 2.9 hereof; and provided further, however, that the Borrower’s failure to confirm any telephonic notice with a written notice shall not invalidate any notice so given if acted upon by the Administrative Agent. Any prepayment hereunder shall be in amounts of not less than $2,000,000.00 and in an integral multiple of $1,000,000.00. Amounts prepaid pursuant to this

-26-

Section 2.6(a) may, with respect to the Revolving Loans, be reborrowed, subject to the terms and conditions hereof. Amounts prepaid shall be paid together with accrued interest on the amount so prepaid.

(b) Repayments. The Borrower shall repay the Loans as follows:

(i) Revolving Loans and Letter of Credit Obligations in Excess of Revolving Loan Commitments. If, at any time, the amount of the sum of the Revolving Loans and Letter of Credit Obligations (or, if applicable, the Incremental Facility Loans) shall exceed the Revolving Loan Commitments (or, if applicable, the Incremental Facility Commitments), the Borrower shall, on such date and subject to Section 2.9 hereof, make a repayment of the principal amount of the Revolving Loans (or, if applicable, the Incremental Facility Loans), or, if there are no such Loans then outstanding, establish, if applicable, a Letter of Credit Reserve Account, in each case, in an amount equal to such excess, together with any accrued interest and fees with respect thereto.

(ii) Unreinvested Net Proceeds from Asset Sales and Insurance and Condemnation Proceedings. At any time after the aggregate Unreinvested Net Proceeds from all sales, transfers or other dispositions of assets of the Credit Parties or from any insurance or condemnation proceeding in respect of such assets after the Agreement Date exceeds $10,000,000.00, the Loans shall be repaid in an amount equal to, in the aggregate, such Unreinvested Net Proceeds. The amount of the Unreinvested Net Proceeds required to be repaid under this Section 2.6(b)(ii) shall be applied first, to any Term Loan A Loans and DDT Loans then outstanding, on a pro rata basis, second, once the outstanding Term Loan A Loans and DDT Loans are paid in full, to any Revolving Loans then outstanding (without a reduction in the Revolving Loan Commitments) and third, once the outstanding Revolving Loans are paid in full, as a reduction of the DDTL Commitments. Accrued interest on the principal amount of the Loans being repaid pursuant to this Section 2.6(b)(ii) to the date of such repayment will be paid by the Borrower concurrently with such principal repayment.

(iii) Maturity Date. In addition to the foregoing, a final payment of all Loans, together with accrued interest and fees with respect thereto, shall be due and payable on the Maturity Date.

Section 2.7 Notes; Loan Accounts.

(a) The Loans shall be repayable in accordance with the terms and provisions set forth herein and, if requested, shall be evidenced by the Notes. One (1) Revolving Loan Note, one (1) Term Loan A Note, one (1) DDTL Note and, if applicable, one (1) Incremental Facility Note, shall be payable to each applicable Lender in accordance with such Lender’s applicable Commitment Ratio for Revolving Loans, the Term Loan A Loans, the DDT Loans and, if applicable, the Incremental Facility Loans. The Notes shall be issued by the Borrower upon the request of any Lender in connection with the Commitments or Loans held by it and shall be duly executed and delivered by one or more Authorized Signatories.

(b) Each Lender may open and maintain on its books in the name of the Borrower a loan account with respect to its portion of the Loans and interest thereon. Each Lender which opens such a loan account shall debit such loan account for the principal amount

-27-

of its portion of each Advance made by it and accrued interest thereon, and shall credit such loan account for each payment on account of principal of or interest on its Loans. The records of a Lender with respect to the loan account maintained by it shall be prima facie evidence of its portion of the Loans and accrued interest thereon absent manifest error, but the failure of any Lender to make any such notations or any error or mistake in such notations shall not affect the Borrower’s repayment obligations with respect to such Loans.

Section 2.8 Manner of Payment.

(a) Each payment (including, without limitation, any prepayment) by the Borrower on account of the principal of or interest on the Loans, commitment fees and any other amount owed to the Lenders or the Administrative Agent or any of them under this Agreement or the Notes shall be made not later than 1:00 p.m. (New York, New York time) on the date specified for payment under this Agreement to the Administrative Agent at the Administrative Agent’s Office, for the account of the Lenders or the Administrative Agent, as the case may be, in lawful money of the United States of America in immediately available funds. Any payment received by the Administrative Agent after 1:00 p.m. (New York, New York time) shall be deemed received on the next Business Day. Receipt by the Administrative Agent of any payment intended for any Lender or Lenders hereunder prior to 1:00 p.m. (New York, New York time) on any Business Day shall be deemed to constitute receipt by such Lender or Lenders on such Business Day. In the case of a payment for the account of a Lender, the Administrative Agent will promptly, but no later than the close of business on the date such payment is deemed received, thereafter distribute the amount so received in like funds to such Lender. If the Administrative Agent shall not have received any payment from the Borrower as and when due, the Administrative Agent will promptly notify the applicable Lenders accordingly. In the event that the Administrative Agent shall fail to make distribution to any Lender as required under this Section 2.8, the Administrative Agent agrees to pay such Lender interest from the date such payment was due until paid at the Federal Funds Rate.

(b) The Borrower agrees to pay principal, interest, fees and all other amounts due hereunder or under the Notes without set-off or counterclaim or any deduction whatsoever.

(c) Prior to the acceleration of the Loans under Section 8.2 hereof, if some but less than all amounts due from the Borrower are received by the Administrative Agent with respect to the Obligations, the Administrative Agent shall distribute such amounts in the following order of priority, all on a pro rata basis to the Lenders: (i) to the payment on a pro rata basis of any fees or expenses then due and payable to the Administrative Agent and the Issuing Bank, or any of them or expenses then due and payable to the Lenders; (ii) to the payment of interest then due and payable on the Loans on a pro rata basis and of fees then due and payable to the Lenders on a pro rata basis; (iii) to the payment of all other amounts not otherwise referred to in this Section 2.8(c) then due and payable to the Administrative Agent, the Issuing Bank and the Lenders, or any of them, hereunder or under the Notes or any other Loan Document; and (iv) to the payment of principal then due and payable on the Loans on a pro rata basis.

(d) Subject to any contrary provisions in the definition of Interest Period, if any payment under this Agreement or any of the other Loan Documents is specified to be made on a day which is not a Business Day, it shall be made on the next Business Day, and

-28-

such extension of time shall in such case be included in computing interest and fees, if any, in connection with such payment.

(e) Each Lender which is not a U.S. Person (a “Non-U.S. Bank”) (or, if such Non-U.S. Bank is not the beneficial owner thereof, such beneficial owner) shall deliver to the Borrower (with a copy to the Administrative Agent) prior to or at the time it receives a Note or Notes for any of its Loans, an Internal Revenue Service Form W-8BEN or W-8ECI (or such successor and related forms as may from time to time be adopted by the relevant taxing authorities of the United States of America), together with an annual certificate stating that such Non-U.S. Bank or beneficial owner, as the case may be, is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code and is not otherwise described in Section 881(c)(3) of the Code. Each Non-U.S. Bank or beneficial owner, as the case may be, shall promptly notify the Borrower (with a copy to the Administrative Agent) if at any time, such Non-U.S. Bank or beneficial owner, as the case may be, determines that it is no longer in a position to make the certification made in such certificate to the Borrower (or any other form of certification adopted by the relevant taxing authorities of the United States of America for such purposes).

Section 2.9 Reimbursement.

(a) Whenever any Lender shall sustain or incur any losses or reasonable out-of-pocket expenses in connection with (i) the failure by the Borrower to borrow, Continue or Convert any LIBOR Advance after having given notice of its intention to borrow, Continue or Convert such Advance in accordance with Section 2.2 hereof (whether by reason of the Borrower’s election not to proceed or the non-fulfillment of any of the conditions set forth in Article 3 hereof), or (ii) the prepayment other than on the applicable Payment Date (or failure to prepay after giving notice thereof) of any LIBOR Advance in whole or in part for any reason, the Borrower agrees to pay to such Lender, upon such Lender’s demand, an amount sufficient to compensate such Lender for all such losses and out-of-pocket expenses. Such Lender’s good faith determination of the amount of such losses or out-of-pocket expenses, as set forth in writing and accompanied by calculations in reasonable detail demonstrating the basis for its demand, shall be presumptively correct absent manifest error.

(b) Losses subject to reimbursement hereunder shall include, without limiting the generality of the foregoing, lost margins, expenses incurred by any Lender or any participant of such Lender permitted hereunder in connection with the re-employment of funds prepaid, paid, repaid, not borrowed, or not paid, as the case may be, and will be payable whether the Maturity Date is changed by virtue of an amendment hereto (unless such amendment expressly waives such payment) or as a result of acceleration of the Loans.

Section 2.10 Pro Rata Treatment.

(a) Advances. Each Advance under the Revolving Loan Commitments from the Lenders hereunder shall be made pro rata on the basis of the applicable Commitment Ratios of the Lenders having a Revolving Loan Commitment. Each Advance under the DDTL Commitments from the Lenders hereunder shall be made on a pro rata basis of the applicable Commitment Ratios of the Lenders having DDTL Commitments.

(b) Payments. Except as provided in Section 2.2(e) hereof and Article 10 hereof, each payment and prepayment of principal of, and interest on, the Loans shall be made to the Lenders pro rata on the basis of their respective unpaid principal amounts

-29-

outstanding under the applicable Loans immediately prior to such payment or prepayment. If any Lender shall obtain any payment (whether involuntary, through the exercise of any right of set-off, or otherwise) on account of the Loans in excess of its ratable share of the Loans under its applicable Commitment Ratio, such Lender shall forthwith purchase from the other Lenders such participations in the portion of the applicable Loans made by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and each such other Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery. The Borrower agrees that any Lender so purchasing a participation from another Lender pursuant to this Section 2.10(b) may, to the fullest extent permitted by law, exercise all its rights of payment (including, without limitation, the right of set-off) with respect to such participation as fully as if such purchasing Lender were the direct creditor of the Borrower in the amount of such participation.

(c) Commitment Reductions. Any reduction of the Revolving Loan Commitments required or permitted hereunder shall reduce the Revolving Loan Commitment of each Lender having a Revolving Loan Commitment on a pro rata basis based on the Commitment Ratio of such Lender for the Revolving Loan Commitment. Any reduction of the DDTL Commitments required or permitted hereunder shall reduce the DDTL Commitment of each Lender having a DDTL Commitment on a pro rata basis based on the Commitment Ratio of such Lender for the DDTL Commitment. Any reduction of any Incremental Facility Commitment required or permitted hereunder shall reduce the Incremental Facility Commitment of each Lender having such Incremental Facility Commitment on a pro rata basis based on the Commitment Ratio of such Lender for such Incremental Facility Commitment.

Section 2.11 Capital Adequacy. If after the date hereof, the adoption of any Applicable Law regarding the capital adequacy of banks or bank holding companies, or any change in Applicable Law (whether adopted before or after the Agreement Date) or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by such Lender (or the bank holding company of such Lender) with any directive regarding capital adequacy (whether or not having the force of law) of any such governmental authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on any Lender’s capital as a consequence of its obligations hereunder with respect to the Loans and the Commitments to a level below that which it could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s policies with respect to capital adequacy immediately before such adoption, change or compliance and assuming that such Lender’s (or the bank holding company of such Lender) capital was fully utilized prior to such adoption, change or compliance) by an amount reasonably deemed by such Lender to be material, then, upon demand by such Lender, the Borrower shall promptly pay to such Lender such additional amounts as shall be sufficient to compensate such Lender (on an after-tax basis) for such reduced return, together with interest on such amount from the fourth (4th) Business Day after the date of demand or the Maturity Date, as applicable, until payment in full thereof at the Default Rate. A certificate of such Lender setting forth the amount to be paid to such Lender by the Borrower as a result of any event referred to in this paragraph and supporting calculations in reasonable detail shall be presumptively correct absent manifest error.

Section 2.12 Lender Tax Forms.

To the extent permitted by applicable U.S. Federal law, each such Lender agrees to provide the Administrative Agent and the Borrower with new forms prescribed by the Internal Revenue Service upon the expiration or obsolescence of any previously delivered form, or after the occurrence of any event requiring a change in the most recent forms delivered by it to the Administrative Agent and the Borrower.

(b) On or prior to the Agreement Date, and to the extent permitted by applicable U.S. Federal law, on or prior to the first Business Day of each calendar year thereafter, each Lender which is a U.S. Person shall provide the Administrative Agent and the Borrower a duly completed and executed copy of the Internal Revenue Service Form W-9 or successor form to the effect that it is a U.S. Person.

Section 2.13 Letters of Credit.

(a) Subject to the terms and conditions hereof, the Issuing Bank, on behalf of the Lenders having a Revolving Loan Commitment, and in reliance on the agreements of such Lenders set forth in Section 2.13(d) hereof, hereby agrees to issue one or more Letters of Credit up to an aggregate face amount equal to the Available Letter of Credit Commitment determined immediately prior to giving effect to the issuance thereof; provided, however, that the Issuing Bank shall not issue any Letter of Credit (i) unless the conditions precedent to the issuance thereof set forth in Section 3.3 hereof have been satisfied, (ii) if any Default then exists or would be caused thereby, (iii) if, after giving effect to such issuance, the Available Revolving Loan Commitment would be less than zero or (iv) within thirty (30) days preceding the Maturity Date; and provided further, however, that at no time shall the aggregate amount of the Letter of Credit Obligations outstanding hereunder exceed $50,000,000.00. Each Letter of Credit shall (A) be payable at sight, (B) be denominated in United States dollars, (C) expire, (i) with respect

-31-

to Standby Letters of Credit, no later than the earlier to occur of (x) the fifth Business Day preceding the Maturity Date and (y) 360 days after its date of issuance (but may contain provisions for automatic renewal; provided that no Default or Event of Default exists on the renewal date or would be caused by such renewal), and (ii) with respect to Commercial Letters of Credit, no later than the earlier to occur of (x) the thirtieth day preceding the Maturity Date and (y) 180 days after its date of issuance (but may contain provisions for automatic renewal; provided that no Default or Event of Default exists on the renewal date or would be caused by such renewal). Each Letter of Credit shall be subject to the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500 and, to the extent not inconsistent therewith, the laws of the State of New York. The Issuing Bank shall not at any time be obligated to issue, or cause to be issued, any Letter of Credit if such issuance would conflict with, or cause the Issuing Bank to exceed any limits imposed by, any Applicable Law. If a Letter of Credit provides that it is automatically renewable unless notice is given by the Issuing Bank that it will not be renewed, the Issuing Bank shall not be bound to give a notice of non-renewal unless directed to do so by Lenders having in the aggregate more than fifty percent (50%) of the Revolving Loan Commitment at least sixty-five (65) days prior to the then scheduled expiration date of such Letter of Credit. It is hereby agreed that the Letters of Credit set forth on Schedule 2 attached hereto are Letters of Credit issued hereunder for all purposes hereunder notwithstanding anything herein that may be construed to the contrary.

(b) The Borrower may from time to time request the Issuing Bank to issue Letters of Credit. Such Borrower shall execute and deliver to the Administrative Agent and the Issuing Bank a Request for Issuance of Letter of Credit for each Letter of Credit to be issued by the Issuing Bank not later than 12:00 noon (New York, New York time) on the fifth (5th) Business Day preceding the date on which the requested Letter of Credit requested is to be issued, or such shorter notice as may be acceptable to the Issuing Bank and the Administrative Agent. Upon receipt of any such Request for Issuance of Letter of Credit, subject to satisfaction of all conditions precedent thereto as set forth in Section 3.3 hereof, the Issuing Bank shall process such Request for Issuance of Letter of Credit and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly issue the Letter of Credit requested thereby. The Issuing Bank shall furnish a copy of such Letter of Credit (or any amendment thereto or renewal or extension thereof) to the Borrower, the Administrative Agent and each of the Lenders following the issuance thereof. The Borrower shall pay or reimburse the Issuing Bank for normal and customary costs and expenses incurred by the Issuing Bank in issuing, effecting payment under, amending or otherwise administering the Letters of Credit.

(c) At such time as the Administrative Agent shall be notified by the Issuing Bank that the beneficiary under any Letter of Credit has drawn on the same, the Administrative Agent shall promptly notify the Borrower and each Lender having a Revolving Loan Commitment, by telephonic notice, followed promptly by written notice, of the amount of the draw and, in the case of each such Lender, such Lender’s portion of such draw amount as calculated in accordance with its respective Commitment Ratio under the Revolving Loan Commitment.

(d) The Borrower hereby agrees to immediately reimburse the Issuing Bank for amounts paid by the Issuing Bank in respect of draws under a Letter of Credit issued at

-32-

the Borrower’s request. In order to facilitate such repayment, the Borrower hereby irrevocably requests the Lenders having a Revolving Loan Commitment, and such Lenders hereby severally agree, on the terms and conditions of this Agreement (other than as provided in Article 2 hereof with respect to the amounts of, the timing of requests for, and the repayment of Advances hereunder and in Article 3 hereof with respect to conditions precedent to Advances hereunder), with respect to any honoring of any draw under a Letter of Credit prior to the occurrence of an Event of Default under Section 8.1(f) or (g) hereof, to make an Advance (which Advance may be a LIBOR Advance if the Borrower so requests in a timely manner or may be Converted to a LIBOR Advance as provided in the Loan Agreement) to the Borrower on each day on which the Issuing Bank honors a draw made under any Letter of Credit and in the amount of such draw, and to pay the proceeds of such Advance directly to the Issuing Bank to reimburse the Issuing Bank for the amount paid by it upon such draw. Each Lender having a Revolving Loan Commitment shall pay its share of such Advance by paying its portion of such Advance to the Administrative Agent in accordance with Section 2.2(e) hereof and its respective Commitment Ratio under the Revolving Loan Commitments, without reduction for any set-off or counterclaim of any nature whatsoever and regardless of whether any Default or Event of Default (other than with respect to an Event of Default under Section 8.1(f) or (g) hereof) then exists or would be caused thereby. If at any time that any Letters of Credit are outstanding, any of the events described in clauses of Section 8.1(f) or (g) hereof shall have occurred and be continuing, then each Lender having a Revolving Loan Commitment shall, automatically upon the occurrence of any such event and without any action on the part of the Issuing Bank, the Borrower, the Administrative Agent or such Lenders, be deemed to have purchased an undivided participation in the face amount of all Letters of Credit then outstanding in an amount equal to such Lender’s respective Commitment Ratio under the Revolving Loan Commitments, and each Lender having a Revolving Loan Commitment shall, notwithstanding such Event of Default, upon a drawing being honored under any Letter of Credit, immediately pay to the Administrative Agent for the account of the Issuing Bank, in immediately available funds, the amount of such Lender’s participation (and the Issuing Bank shall deliver to such Lender a loan participation certificate dated the date of the occurrence of such event and in the amount of such Lender’s respective Commitment Ratio under the Revolving Loan Commitments). The disbursement of funds in connection with a draw under a Letter of Credit pursuant to this Section 2.13(d) shall be subject to the terms and conditions of Section 2.2(e) hereof. The obligation of each Lender having a Revolving Loan Commitment to make payments to the Administrative Agent, for the account of the Issuing Bank, in accordance with this Section 2.13 shall be absolute and unconditional and no such Lender shall be relieved of its obligations to make such payments by reason of non-compliance by any other Person with the terms of the Letter of Credit or for any other reason. The Administrative Agent shall promptly remit to the Issuing Bank the amounts so received from the other Lenders. Any overdue amounts payable by the Lenders having a Revolving Loan Commitment to the Issuing Bank in respect of a draw under any Letter of Credit shall bear interest, payable on demand, at the rate on overnight Federal funds transactions with members of the Federal Reserve System arranged by Federal funds brokers, as published for such day by the Federal Reserve Bank of New York.

(e) The Borrower agrees that any action taken or omitted to be taken by the Issuing Bank in connection with any Letter of Credit, except for such actions or omissions as shall constitute gross negligence or willful misconduct on the part of the Issuing Bank, shall be binding on the Borrower as between the Borrower and the Issuing Bank, and shall not result

-33-

in any liability of the Issuing Bank to the Borrower. The obligation of the Borrower to reimburse the Lenders for Advances made to reimburse the Issuing Bank for draws under the Letter of Credit shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of this Agreement under all circumstances whatsoever, including, without limitation, the following circumstances:

(i) any lack of validity or enforceability of any Loan Document;

(ii) any amendment or waiver of or consent to any departure from any or all of the Loan Documents;

(iii) any improper use which may be made of any Letter of Credit or any improper acts or omissions of any beneficiary or transferee of any Letter of Credit in connection therewith;

(iv) the existence of any claim, set-off, defense or any right which the Borrower may have at any time against any beneficiary or any transferee of any Letter of Credit (or Persons for whom any such beneficiary or any such transferee may be acting) or any Lender (other than the defense of payment to such Lender in accordance with the terms of this Agreement) or any other Person, whether in connection with any Letter of Credit, any transaction contemplated by any Letter of Credit, this Agreement, any other Loan Document, or any unrelated transaction;

(v) any statement or any other documents presented under any Letter of Credit proving to be insufficient, forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect whatsoever; provided that the same shall not have resulted from gross negligence or willful misconduct of the Issuing Bank;

(vi) the insolvency of any Person issuing any documents in connection with any Letter of Credit;

(vii) any breach of any agreement between the Borrower and any beneficiary or transferee of any Letter of Credit; provided that the same shall not have resulted from the gross negligence or willful misconduct of the Issuing Bank;

(viii) any irregularity in the transaction with respect to which any Letter of Credit is issued, including any fraud by the beneficiary or any transferee of such Letter of Credit; provided that the same shall not have resulted from the gross negligence or willful misconduct of the Issuing Bank;

(ix) any errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, wireless or otherwise, whether or not they are in code; provided that the same shall not have resulted from the gross negligence or willful misconduct of the Issuing Bank;

(x) any act, error, neglect or default, omission, insolvency or failure of business of any of the correspondents of the Issuing Bank; provided that the same shall not have resulted from the gross negligence or willful misconduct of the Issuing Bank;

-34-

(xi) any other circumstances arising from causes beyond the control of the Issuing Bank;

(xii) payment by the Issuing Bank under any Letter of Credit against presentation of a sight draft or a certificate which does not comply with the terms of such Letter of Credit; provided that the same shall not have resulted from gross negligence or willful misconduct of the Issuing Bank; and

(xiii) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing; provided that the same shall not have resulted from the result of gross negligence or willful misconduct of the Issuing Bank or any other Lender.

(f) If any change in Applicable Law, any change in the interpretation or administration thereof, or any change in compliance with Applicable Law by the Issuing Bank or any Lender having a Revolving Loan Commitment as a result of any official request or directive of any governmental authority, central bank or comparable agency (whether or not having the force of law) shall (i) impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System), special deposit, capital adequacy, assessment or other requirements or conditions against Letters of Credit issued by the Issuing Bank or against participations by any other Lender in the Letters of Credit or (ii) impose on the Issuing Bank or any other Lender any other condition regarding any Letter of Credit or any participation therein (other than with respect to Taxes, which shall be governed exclusively by Section 10.3), and the result of any of the foregoing in the reasonable determination of the Issuing Bank or such Lender, as the case may be, is to increase the cost to the Issuing Bank or such Lender of issuing or maintaining any Letter of Credit or purchasing or maintaining any participation therein, as the case may be, by an amount (which amount shall be reasonably determined) deemed by the Issuing Bank or such Lender to be material, and the designation of a different lending office will not avoid the need for additional compensation (without creating other unreimbursed costs or disadvantage to such Lender), then, on request by the Issuing Bank or such Lender, the Borrower shall pay, within ten (10) days after demand, the Issuing Bank or such Lender, as the case may be, such additional amount or amounts as the Issuing Bank or such Lender, as the case may be, so determines will compensate it on an after-tax basis for such increased costs. A certificate of the Issuing Bank or such Lender setting forth the amount, and in reasonable detail the basis for the Issuing Bank or such Lender’s determination of such amount, to be paid to the Issuing Bank or such Lender by the Borrower as a result of any event referred to in this paragraph shall, absent manifest error, be conclusive.

(g) Each Lender having a Revolving Loan Commitment shall be responsible for its pro rata share (based on such Lender’s respective Commitment Ratio under the Revolving Loan Commitments) of any and all reasonable out-of-pocket costs, expenses (including reasonable legal fees) and disbursements which may be incurred or made by the Issuing Bank in connection with the collection of any amounts due under, the administration of, or the presentation or enforcement of any rights conferred by any Letter of Credit, the Borrower’s or any guarantor’s obligations to reimburse or otherwise. In the event the Borrower shall fail to pay such expenses of the Issuing Bank within ten (10) days after demand for payment by the Issuing Bank, each Lender having a Revolving Loan Commitment shall thereupon pay to the Issuing Bank its pro rata share (based on such Lender’s respective Commitment Ratio under the

-35-

Revolving Loan Commitments) of such expenses within five (5) days from the date of the Issuing Bank’s notice to the Lenders having a Revolving Loan Commitment of the Borrower’s failure to pay; provided, however, that if the Borrower or any guarantor shall thereafter pay such expense, the Issuing Bank will repay to each Lender having a Revolving Loan Commitment the amounts received from such Lender hereunder.

(h) The Borrower agrees that each Advance by the Lenders having Revolving Loan Commitments to reimburse the Issuing Bank for draws under any Letter of Credit, shall, for all purposes hereunder, be deemed to be an Advance under the Revolving Loan Commitment to the Borrower and shall be payable and bear interest in accordance with all other Revolving Loans to the Borrower.

(i) The Borrower will indemnify and hold harmless the Administrative Agent, the Issuing Bank and each Lender and each of the foregoing Person’s respective employees, representatives, officers and directors from and against any and all claims, liabilities, obligations, losses (other than loss of profits), damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever (including reasonable attorneys’ fees, but excluding Taxes, which shall be governed exclusively by Section 10.3) which may be imposed on, incurred by or asserted against the Administrative Agent, the Issuing Bank or any such other Lender in any way relating to or arising out of the issuance of a Letter of Credit, except that the Borrower shall not be liable to the Administrative Agent, the Issuing Bank or any such Lender for any portion of such claims, liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses, or disbursements resulting from the gross negligence or willful misconduct of the Person seeking indemnification as determined by a non-appealable judicial order. This Section 2.13(i) shall survive termination of this Agreement.

Section 2.14 Incremental Facility Advances.

(a) Subject to the terms and conditions of this Agreement, the Borrower may request an Incremental Facility Commitment (which may be in the form of a revolver or term loan) on any Business Day; provided, however, that (i) the Borrower may not request any Incremental Facility Commitment or an Incremental Facility Advance after the occurrence and during the continuance of a Default or an Event of Default, including, without limitation, any Default or Event of Default that would result after giving effect to any Incremental Facility Advance and (ii) the aggregate amount of such Incremental Facilities shall not exceed $250,000,000.00. No Incremental Facility Loans shall have a maturity date earlier than the Maturity Date. The decision of any Lender to provide an Incremental Facility Commitment to the Borrower shall be at such Lender’s sole discretion and shall be made in writing. The Incremental Facility Commitment of a Lender providing an Incremental Facility Commitment shall, at the request of such Lender, be evidenced by an Incremental Facility Note. Persons not then Lenders may be included as Lenders holding a portion of such Incremental Facility Commitment with the written approval of the Borrower and the Administrative Agent (such approval not to be unreasonably withheld, delayed, or conditioned). The Incremental Facility Commitments shall be governed by this Agreement and the other Loan Documents and be on terms and conditions no more restrictive than those set forth herein and therein. The terms and conditions in this Section 2.14 may be amended with the consent of the Majority Lenders and the Borrower, except to the extent that a specific Lender’s consent is otherwise required with respect to an issuance by such Lender of any Incremental Facility Commitment.

-36-

(b) Prior to the effectiveness of any Incremental Facility Commitment, the Borrower shall (i) deliver to the Administrative Agent and the Lenders a Notice of Incremental Facility Commitment; and (ii) provide revised projections to the Administrative Agent and the Lenders, which shall be in form and substance reasonably satisfactory to the Administrative Agent and which shall demonstrate the Borrower’s ability to timely repay such Incremental Facility Commitment and any Incremental Facility Advances thereunder and to comply with the covenants contained in Sections 7.5 and 7.6 hereof.

(c) Incremental Facility Advances (i) shall bear interest at the Base Rate Basis or the LIBOR Basis; provided, however that the Applicable Margin with respect thereto shall be as agreed to by the Borrower and the Lenders making such Incremental Facility Advances and (ii) subject to Section 2.14(a) hereof, shall be repaid as agreed to by the Borrower and the Lenders making such Incremental Facility Advances.

(d) Incremental Facility Advances (and Continuations and Conversions thereof) shall be requested by the Borrower pursuant to a request (which shall be in substantially the form of a Request for Advance) delivered in the same manner as a Request for Advance, but (in the case of Incremental Facility Advances) shall be funded pro rata only by those Lenders holding an Incremental Facility Commitment.

Section 9.3 Consultation with Counsel.

Section 9.6 Responsibility of the Administrative Agent and Issuing Bank. The duties and obligations of the Administrative Agent and the Issuing Bank under this Agreement are only those expressly set forth in this Agreement. The Administrative Agent shall be entitled to assume that no Default or Event of Default has occurred and is continuing unless it has actual knowledge, or has been notified in writing by the Borrower, of such fact, or has been notified by a Lender in writing that such Lender considers that a Default or an Event of Default has occurred and is continuing, and such Lender shall specify in detail the nature thereof in writing. The Administrative Agent and the Issuing Bank shall not be liable hereunder for any action taken or omitted to be taken except for its own respective gross negligence or willful misconduct as determined by a final, non-appealable judicial order of a court of competent jurisdiction.

The Administrative Agent shall incur no liability under or in respect of this Agreement with respect to anything which it may do or refrain from doing in the reasonable exercise of its judgment or which may seem to it to be necessary or desirable in the circumstances, except for its gross negligence or willful misconduct as determined by a final, non-appealable judicial order of a court having jurisdiction over the subject matter.

notified, of any Default or Event of Default, the Administrative Agent, such Lender or the Issuing Bank shall promptly notify the Lenders (provided, however, that the failure to give such notice shall not result in any liability on the part of such Lender, the Issuing Bank or the Administrative Agent), and the Administrative Agent shall take such action and assert such rights under this Agreement and the other Loan Documents as the Majority Lenders shall request in writing, and the Administrative Agent shall not be subject to any liability by reason of its acting pursuant to any such request. If the Majority Lenders shall fail to request the Administrative Agent to take action or to assert rights under this Agreement or any other Loan Documents in respect of any Default or Event of Default within ten (10) days after their receipt of the notice of any Default or Event of Default from the Administrative Agent, any Lender or the Issuing Bank, or shall request inconsistent action with respect to such Default or Event of Default, the Administrative Agent may, but shall not be required to, take such action and assert such rights (other than rights under Article 8 hereof) as it deems in its discretion to be advisable for the protection of the Lenders, except that, if the Majority Lenders have instructed the Administrative Agent not to take such action or assert such right, in no event shall the Administrative Agent act contrary to such instructions, unless time is of the essence, in which case, the Administrative Agent may act in accordance with its reasonable discretion.

Section 9.9 Responsibility Disclaimed. The Administrative Agent shall not be under any liability or responsibility whatsoever as the Administrative Agent:

(a) in making its decision to enter into this Agreement and to make its portion of the Loans it has independently taken whatever steps it considers necessary to evaluate the financial condition and affairs of the Borrower and that it has made an independent credit judgment, and that it has not relied upon the Administrative Agent or information provided by the Administrative Agent (other than information provided to the Administrative Agent by the Borrower and forwarded by the Administrative Agent to the Lenders); and

(b) so long as any portion of the Loans remains outstanding or such Lender has an obligation to make its portion of Advances hereunder, it will continue to make its own independent evaluation of the financial condition and affairs of the Borrower.

Section 9.12 Successor Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided below, the Administrative Agent may resign at any time by giving written notice thereof to the Lenders, the Issuing Bank and the Borrower and may be removed at any time for cause by the Majority Lenders. Upon any such resignation or removal, the Majority Lenders shall have the right to appoint a successor Administrative Agent which appointment shall, prior to a Default, be subject to the consent of the Borrower, acting reasonably. If (a) no successor Administrative Agent shall have been so appointed by the Majority Lenders or (b) appointed, no successor Administrative Agent shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gave notice of resignation or the Majority Lenders removed the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall be any Lender or a commercial bank organized under the laws of the United States of America or any political subdivision thereof which has combined capital and reserves in excess of $250,000,000.00 and which shall be reasonably acceptable to the Borrower. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges, duties and obligations of the retiring Administrative Agent and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents. After any retiring Administrative Agent’s resignation or removal hereunder as Administrative Agent the provisions of this Article shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Administrative Agent. In the event that the Administrative Agent or any of its respective Affiliates ceases to be a Lender hereunder, such Person shall resign its agency hereunder.

reasonable care, and shall be entitled to advice of counsel concerning all matters pertaining to such duties.

Section 9.14 No Responsibilities of the Agents. Notwithstanding any provision to the contrary contained elsewhere herein or in any other Loan Document, the Syndication Agent and the Co-Arrangers (as set forth on the cover page hereof) shall not have any duties or responsibilities, nor shall the Syndication Agent or any of the Co-Arrangers have or be deemed to have any fiduciary relationship with any Lender or participant, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Syndication Agent or any of the Co-Arrangers.

ARTICLE 10 - CHANGES IN CIRCUMSTANCES

AFFECTING LIBOR ADVANCES AND INCREASED COSTS

Section 10.1 LIBOR Basis Determination Inadequate or Unfair. If with respect to any proposed LIBOR Advance for any Interest Period, the Administrative Agent determines after consultation with the Lenders that adequate and fair means do not exist for determining the LIBOR Basis, the Administrative Agent shall forthwith give notice thereof to the Borrower and the Lenders, whereupon until the Administrative Agent notifies the Borrower that the circumstances giving rise to such situation no longer exist, the obligations of any affected Lender to make its portion of such LIBOR Advances shall be suspended and each affected Lender shall make its portion of such LIBOR Advance as a Base Rate Advance.

Section 10.2 Illegality. If after the date hereof, the adoption of any Applicable Law, or any change in any Applicable Law (whether adopted before or after the Agreement Date), or any change in interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender with any directive (whether or not having the force of law) of any such authority, central bank or comparable agency, shall make it unlawful or impossible for any Lender to make, maintain or fund its portion of LIBOR Advances, such Lender shall so notify the Administrative Agent, and the Administrative Agent shall forthwith give notice thereof to the other Lenders and the Borrower. Before giving any notice to the Administrative Agent pursuant to this Section 10.2, such Lender shall designate a different lending office if such designation will avoid the need for giving such notice and will not, in the sole reasonable judgment of such Lender, be otherwise materially disadvantageous to such Lender. Upon receipt of such notice, notwithstanding anything contained in Article 2 hereof, the Borrower shall repay in full the then outstanding principal amount of such Lender’s portion of each affected LIBOR Advance, together with accrued interest thereon, on either (a) the last day of the then current Interest Period applicable to such affected LIBOR Advances if such Lender may lawfully continue to maintain and fund its portion of such LIBOR Advance to such day or (b) immediately if such Lender may not lawfully continue to fund and maintain its portion of such affected LIBOR Advances to such day. Concurrently with repaying such portion of each affected LIBOR Advance, the Borrower may borrow a Base Rate Advance from such Lender, whether or not it would have been entitled to effect such borrowing, and such Lender shall make such Advance, if so requested, in an amount such that the outstanding principal amount of the Advance shall equal

-61-

the outstanding principal amount of the affected LIBOR Advance of such Lender immediately prior to such repayment.

Section 10.3 Increased Costs and Additional Amounts.

(a) If after the date hereof, the adoption of any Applicable Law, or any change in any Applicable Law (whether adopted before or after the Agreement Date), or any interpretation or change in interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof or compliance by any Lender with any directive issued after the Agreement Date (whether or not having the force of law) of any such authority, central bank or comparable agency:

(i) shall subject any Lender to any Tax with respect to its obligation to make its portion of LIBOR Advances, or its portion of other Advances, or shall change the basis of taxation of payments to any Lender of the principal of or interest on its portion of LIBOR Advances or in respect of any other amounts due under this Agreement, or its obligation to make its portion of Advances (except for changes with respect to Taxes imposed on the revenues or net income of such Lender, and except for any Taxes referred to in Section 10.3(b) hereof); or

(ii) shall impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System, but excluding any included in an applicable Eurodollar Reserve Percentage), special deposit, capital adequacy, assessment or other requirement or condition against assets of, deposits with or for the account of, or commitments or credit extended by, any Lender or shall impose on any Lender or the London interbank borrowing market any other condition affecting its obligation to make its portion of such LIBOR Advances or its portion of existing Advances;

and the result of any of the foregoing is to increase the cost to such Lender of making or maintaining any of its portion of LIBOR Advances, or to reduce the amount of any sum received or receivable by such Lender under this Agreement or under its Note, if any, with respect thereto, then, within ten (10) days after demand by such Lender, the Borrower agrees to pay to such Lender such additional amount or amounts as will compensate such Lender on an after-tax basis for such increased costs.

(b) All payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income or other similar taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Taxes”), now or hereafter imposed, levied, collected, withheld or assessed by any governmental authority, excluding net income Taxes and franchise Taxes (imposed in lieu of net income Taxes) imposed on any Lender as a result of present or former connection between such Person and the jurisdiction of the governmental authority imposing such Tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from such Person having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other Loan Document). If any such non-excluded Taxes (collectively, the “Non-Excluded Taxes”) are required to be withheld from any amounts payable to any Lender hereunder, the amounts so payable to such Person shall be increased to the

-62-

extent necessary to yield to such Person (after payment of all Non-Excluded Taxes) interest on any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement; provided, however, that the Borrower shall not be required to increase any such amounts payable to any Lender if such Person fails to comply with the requirements of Section 2.12 hereof. Whenever any Non-Excluded Taxes are payable by the Borrower, as promptly as possible thereafter the Borrower shall send to the Administrative Agent for its own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the Borrower fails to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other documentary evidence, the Borrower shall indemnify the Administrative Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Administrative Agent or any Lender as result of any such failure. The Borrower shall make any payments required pursuant to the immediately preceding sentence within thirty (30) days after receipt of written demand therefor from the Administrative Agent or any Lender, as the case may be. The agreements set forth in this Section 10.3 shall survive the termination of this Agreement and the payment of the Obligations. Each Lender will promptly notify the Borrower and the Administrative Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Lender to compensation pursuant to this Section 10.3 and will designate a different lending office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole reasonable judgment of such Lender made in good faith, be otherwise disadvantageous to such Lender. Notwithstanding any provision herein to the contrary, the Borrower shall have no obligation to pay to any Lender any amount which the Borrower is liable to withhold due to the failure of such Lender to file any statement of exemption required under the Code in order to permit the Borrower to make payments to such Lender without such withholding.

(c) Any Lender claiming compensation under this Section 10.3 shall provide the Borrower with a written certificate setting forth the additional amount or amounts to be paid to it hereunder and calculations therefor in reasonable detail. Such certificate shall be presumptively correct absent manifest error. In determining such amount, such Lender may use any reasonable averaging and attribution methods. If any Lender demands compensation under this Section 10.3, the Borrower may at any time, upon at least five (5) Business Days’ prior notice to such Lender, prepay in full such Lender’s portion of the then outstanding LIBOR Advances, together with accrued interest and fees thereon to the date of prepayment, along with any reimbursement required under Section 2.9 hereof and this Section 10.3. Concurrently with prepaying such portion of LIBOR Advances the Borrower may, whether or not then entitled to make such borrowing, borrow a Base Rate Advance, or a LIBOR Advance not so affected, from such Lender, and such Lender shall, if so requested, make such Advance in an amount such that the outstanding principal amount of such Advance shall equal the outstanding principal amount of the affected LIBOR Advance of such Lender immediately prior to such prepayment.

(d) The Borrower shall pay any present or future stamp, transfer or documentary Taxes or any other excise or property Taxes that may be imposed in connection with the execution, delivery or registration of this Agreement or any other Loan Documents.

Section 10.4 Effect On Other Advances. If notice has been given pursuant to Section 10.1, 10.2 or 10.3 hereof suspending the obligation of any Lender to make its portion of any type of LIBOR Advance, or requiring such Lender’s portion of LIBOR Advances to be repaid or

-63-

prepaid, then, unless and until such Lender notifies the Borrower that the circumstances giving rise to such repayment no longer apply, all amounts which would otherwise be made by such Lender as its portion of LIBOR Advances shall be instead as Base Rate Advances, unless otherwise notified by the Borrower.

Section 10.5 Claims for Increased Costs and Taxes; Replacement Lenders. In the event that any Lender shall decline to make LIBOR Advances pursuant to Sections 10.1 and 10.2 hereof or shall have notified the Borrower that it is entitled to claim compensation pursuant to Section 10.3, 2.8, 2.9 or 2.11 hereof or is unable to complete the form required or is subject to withholding on account of any Tax (each such lender being an “Affected Lender”), the Borrower at its own cost and expense may designate a replacement lender (a “Replacement Lender”) to assume the DDTL Commitments and/or Revolving Loan Commitments and/or Incremental Facility Commitments and the obligations of any such Affected Lender hereunder, and to purchase the outstanding Loans of such Affected Lender and such Affected Lender’s rights hereunder and with respect thereto, and within ten (10) Business Days of such designation the Affected Lender shall (a) sell to such Replacement Lender, without recourse upon, warranty by or expense to such Affected Lender, by way of an Assignment and Assumption Agreement substantially in the form of Exhibit S attached hereto, for a purchase price equal to (unless such Lender agrees to a lesser amount) the outstanding principal amount of the Loans of such Affected Lender, plus all interest accrued and unpaid thereon and all other amounts owing to such Affected Lender hereunder, including without limitation, payment by the Borrower of any amount which would be payable to such Affected Lender pursuant to Section 2.8 hereof, and (b) assign the DDTL Commitments and/or Revolving Loan Commitments and/or Incremental Facility Commitments of such Affected Lender and upon such assumption and purchase by the Replacement Lender, such Replacement Lender shall be deemed to be a “Lender” for purposes of this Agreement and such Affected Lender shall cease to be a “Lender” for purposes of this Agreement and shall no longer have any obligations or rights hereunder (other than any obligations or rights which according to this Agreement shall survive the termination of the DDTL Commitments and/or Revolving Loan Commitments and/or Incremental Facility Commitments).

(c) For purposes of this Agreement, delivery may also be made by the posting of any required documents, reports, certificates, or other information to the Intralinks system or any other electronic distribution system to which all Lenders have access and provided that all Lenders are notified in writing (or electronically) that such posting has occurred. The Borrower acknowledge that (i) the distribution of material through an electronic medium is not necessarily secure and that there are confidentiality and other risks associated with such distribution, (ii) Intralinks, or any other electronic platform, is provided “as is” and “as available” and (iii) neither the Administrative Agent nor any of its Affiliates warrants the accuracy, adequacy or completeness of Intralinks, or any other electronic platform. No warranty of any kind, express, implied or statutory, including, without limitation, any warranty of merchantability, fitness for a particular purpose, non-infringement of third-party rights or freedom from viruses or other code defects, is made by the Administrative Agent or any of its Affiliates in connection with Intralinks or any other electronic platform.

Section 11.2 Expenses. The Borrower will promptly pay, or reimburse:

(a) all reasonable out-of-pocket expenses of the Administrative Agent in connection with the preparation, negotiation, execution and delivery of this Agreement and the other Loan Documents, and the transactions contemplated hereunder and thereunder any amendments, waivers and consents associated therewith, including, without limitation, the reasonable fees and disbursements of Xxxxxxxxxx Xxxxxxxx XXX, Xxxxxxx, Xxxxxxx, special counsel for the Administrative Agent; and

(b) all reasonable out-of-pocket costs and expenses of the Administrative Agent, the Lenders, the Issuing Bank and the Syndication Agent of enforcement under this Agreement or the other Loan Documents and all reasonable out-of-pocket costs and expenses of collection if an Event of Default occurs in the payment of the Notes, which in each case shall include, without limitation, reasonable fees and out-of-pocket expenses of counsel for the Administrative Agent, each of the Lenders, the Issuing Bank and the Syndication Agent.

Section 11.3 Waivers. The rights and remedies of the Administrative Agent, the Lenders and the Issuing Bank under this Agreement and the other Loan Documents shall be cumulative and not exclusive of any rights or remedies which they would otherwise have. No failure or delay by the Administrative Agent, the Majority Lenders, the Lenders and the Issuing Bank, or any of them, in exercising any right, shall operate as a waiver of such right. No waiver of any provision of this Agreement or consent to any departure by any Credit Party therefrom shall in any event be effective unless the same shall be permitted by Section 11.12, and then such

-66-

waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent or any Lender may have had notice or knowledge of such Default at the time.

Section 11.4 Set-Off. In addition to any rights now or hereafter granted under Applicable Law and not by way of limitation of any such rights, upon the occurrence of an Event of Default and during the continuation thereof, the Administrative Agent, each of the Lenders, Affiliates of any Lender and the Issuing Bank are hereby authorized by the Borrower to the extent permitted by Applicable Law, at any time or from time to time, without notice to the Borrower or to any other Person, any such notice being, to the extent permitted by Applicable Law, hereby expressly waived, to set off and to appropriate and to apply any and all deposits (general or special, time or demand, including, without limitation, Indebtedness evidenced by certificates of deposit, in each case whether matured or unmatured) and any other Indebtedness at any time owing by any such Lender, any Affiliate of any Lender, the Administrative Agent or the Issuing Bank, to or for the credit or the account of the Borrower, against and on account of the obligations and liabilities of the Borrower to the Lenders, the Administrative Agent and the Issuing Bank now or hereafter existing under this Agreement, including, without limitation, all Obligations, the Notes or any other Loan Document, irrespective of whether (a) any Lender, the Administrative Agent or the Issuing Bank, as applicable shall have made any demand hereunder or (b) any Lender, Administrative Agent or the Issuing Bank shall have declared the principal of and interest on the Loans and other amounts due hereunder to be due and payable as permitted by Section 8.2 hereof and although such obligations and liabilities or any of them shall be contingent or unmatured. Upon direction by the Administrative Agent, with the consent of all of the Lenders, each Lender or the Issuing Bank holding deposits of any Credit Party shall, to the extent not prohibited by Applicable Law, exercise its set-off rights as so directed; and, within one (1) Business Day following any such set-off, the Administrative Agent shall give notice thereof to the Borrower. Notwithstanding anything to the contrary contained in this Section 11.4, no Lender nor the Issuing Bank shall exercise any right of set-off without the prior consent of the Majority Lenders so long as the Obligations shall be secured by any real property or real property interest, it being understood and agreed that the provisions of this sentence are for the exclusive benefit of the Lenders and the Issuing Bank, may be amended, modified or waived by the Majority Lenders without notice to or consent of the Borrower or any Subsidiary and shall not constitute a waiver of any rights against the Borrower or any Subsidiary or against any Collateral.

Section 11.5 Assignment and Participation.

(a) The Borrower may not assign or transfer any of its rights or obligations hereunder, under the Notes or under any other Loan Document without the prior written consent of each Lender and the Issuing Bank.

(b) Each Lender may at any time sell assignments or participations of up to one hundred percent (100%) of its interest hereunder to (A) one (1) or more Affiliates of such Lender (provided, however, that if such Affiliate is not a financial institution, such Lender shall be obligated to repurchase such assignment if such Affiliate is unable to honor its obligations hereunder), (B) any Federal Reserve Bank as collateral security pursuant to

-67-

Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank (provided, however, that no such assignment shall relieve such Lender from its obligations hereunder) or (C) any Lender. Notwithstanding the foregoing, no assignee of, or participant with respect to, any interest sold hereunder pursuant to this Section 11.5(b) shall be entitled to receive any greater payment under Section 10.3 than the applicable Lender would have been entitled to receive with respect to the interest sold.

(c) Each Lender may at any time sell assignments or participations to one or more Persons pursuant to which each Lender may assign or participate its interest under this Agreement and the other Loan Documents, including its interest in any particular Advance or portion thereof; provided, however, that (1) all assignments (other than assignments described in Section 11.5(b) hereof) shall be in minimum principal amounts of the lesser of (X) $1,000,000.00 or (Y) the amount of such Lender’s Revolving Loan Commitment, DDTL Commitment, Term Loan A Loans, DDT Loans (with a pro rata portion of any DDTL Commitments then in effect) or Incremental Facility Commitment (in a single assignment only) or Incremental Facility Loan, and (2) all assignments and participations (other than assignments and participations described in Section 11.5(b) hereof) hereunder shall be subject to the following additional terms and conditions:

(i) no assignment shall be sold without the prior consent of the Administrative Agent and, prior to the occurrence and continuation of a Default or Event of Default, the consent of the Borrower, in each case, which consent shall not be unreasonably withheld, delayed or conditioned;

(ii) any Person purchasing a participation or an assignment of any portion of the Loans from any Lender shall be required to represent and warrant that its purchase shall not constitute a “prohibited transaction” (as such term is defined in Section 406 of ERISA or Section 4975 of the Code);

(iii) the Borrower, the Lenders, and the Administrative Agent agree that assignments permitted hereunder (including the assignment of any Advance or portion thereof) may be made with all voting rights, and shall be made pursuant to an Assignment and Assumption Agreement substantially in the form of Exhibit S attached hereto, and an administrative fee of $3,500.00 shall be payable to the Administrative Agent either by the assigning Lender or the assignee thereof at the time of any assignment under this Section 11.5(c);

(iv) no participation agreement shall confer any rights under this Agreement or any other Loan Document to any purchaser thereof, or relieve any issuing Lender from any of its obligations under this Agreement, and all actions hereunder shall be conducted as if no such participation had been granted; provided, however, that any participation agreement may confer on the participant the right to approve or disapprove items requiring consent pursuant to Section 11.12(a)(ii) hereof of an affected Lender for the Loans to which such participation agreement applies;

(v) each Lender agrees to provide the Administrative Agent and the Borrower with prompt written notice of any issuance of assignments of its interests hereunder;

-68-

(vi) no assignment, participation or other transfer of any rights hereunder or under the Notes shall be effected that would result in any interest requiring registration under the Securities Act of 1933, as amended, or qualification under any state securities law;

(vii) no such assignment may be made to any bank or other financial institution (x) with respect to which a receiver or conservator (including, without limitation, the Federal Deposit Insurance Corporation, the Resolution Trust Company or the Office of Thrift Supervision) has been appointed or (y) that is not “adequately capitalized” (as such term is defined in Section 131(b)(1)(B) of the Federal Deposit Insurance Corporation Improvement Act as in effect on the Agreement Date); and

(viii) each Lender shall, and shall cause each of its assignees to, provide to the Administrative Agent on or prior to the effective date of any assignment an appropriate Internal Revenue Service form as provided in Section 2.12 or as otherwise required by Applicable Law supporting such Lender’s or assignee’s position that no withholding by the Borrower or the Administrative Agent for United States income tax payable by such Lender or assignee in respect of amounts received by it hereunder is required. No assignment shall confer any rights to receive any greater payments under Section 10.3 than the applicable Lender would have been entitled to receive with respect to the interest assigned.

(d) Except as specifically set forth in Section 11.5(b) or (c) hereof, nothing in this Agreement or the Notes, expressed or implied, is intended to or shall confer on any Person other than the respective parties hereto and thereto and their successors and assignees permitted hereunder and thereunder any benefit or any legal or equitable right, remedy or other claim under this Agreement or the Notes.

(e) In the case of any participation, all amounts payable by the Borrower under the Loan Documents shall be calculated and made in the manner and to the parties hereto as if no such participation had been sold.

(f) The provisions of this Section 11.5 shall not apply to any purchase of participations among the Lenders pursuant to Section 2.10 hereof.

(g) The Administrative Agent, acting, for this purpose only, as agent of the Borrower shall maintain, at no extra charge to the Borrower, a register (the “Register”) at the address to which notices to the Administrative Agent are to be sent under Section 11.1 hereof on which Register the Administrative Agent shall enter the name, address and taxpayer identification number (if provided) of the registered owner of the Loans evidenced by a Note or, upon the request of the registered owner, for which a Note has been requested. A Note and the Loans evidenced thereby may be assigned or otherwise transferred in whole or in part only by registration of such assignment or transfer of such Note and the Loans evidenced thereby on the Register. Any assignment or transfer of all or part of such Loans and the Note evidencing the same shall be registered on the Register only upon compliance with the other provisions of this Section 11.5 and surrender for registration of assignment or transfer of the Note evidencing such Loans, duly endorsed by (or accompanied by a written instrument of assignment or transfer duly executed by) the registered owner thereof, and thereupon one or more new Notes in the same aggregate principal amount shall be issued to the designated assignee(s) or transferee(s) and, if

-69-

less than the aggregate principal amount of such Notes is thereby transferred, the assignor or transferor. Prior to the due presentment for registration of transfer of any Note, the Borrower and the Administrative Agent shall treat the Person in whose name such Loans and the Note evidencing the same is registered as the owner thereof for the purpose of receiving all payments thereon and for all other purposes, notwithstanding any notice to the contrary.

(h) The Register shall be available for inspection by the Borrower and any Lender, with respect to such Lender’s information, at any reasonable time during the Administrative Agent’s regular business hours upon reasonable prior notice.

(i) Notwithstanding any other provision in this Agreement, any Lender that is a fund that invests in bank loans may, without the consent of the Administrative Agent or the Borrower, pledge all or any portion of its rights under, and interest in, this Agreement and the Notes to any trustee or to any other representative of holders of obligations owed or securities issued, by such fund as security for such obligations or securities; provided, however, that any transfer to any Person upon the enforcement of such pledge or security interest may only be made subject to the assignment provisions of this Section 11.5.

(j) Notwithstanding anything to the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”) sponsored by such Granting Lender, identified as such in writing from time to time by the Granting Lender to the Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Advance that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein shall constitute a commitment by any SPC to make any Advance and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Advance, the Granting Lender shall be obligated to make such Advance pursuant to the terms hereof. The Loans by an SPC hereunder shall be Revolving Loans, Term Loan A Loans, DDT Loans and/or, if applicable, Incremental Facility Loans of the Granting Lender to the same extent, and as if, such Loans were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other senior indebtedness of any SPC, it, solely in its capacity as a party hereto and to any other Loan Document, will not institute against, or join any other person in instituting against, such SPC any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any State thereof. In addition, notwithstanding anything to the contrary contained in this Section 11.5, any SPC may (i) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and without paying any processing fee therefor, assign all or a portion of its interests in any Advances to the Granting Lender or to any financial institutions (consented to by the Borrower and the Administrative Agent) providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Advances and (ii) disclose on a confidential basis any non-public information relating to its Advances to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC. This Section 11.5(j) may not be amended without the written consent of any SPC which has been designated in writing as provided in the first sentence hereof and holds any outstanding Loans. The

-70-

designation by a Granting Lender of an SPC to fund Advances (i) shall be deemed to be a representation, warranty, covenant and agreement by such Granting Lender to the Borrower and all other parties hereunder that (A) the funding and maintaining of such Advances by such SPC shall not constitute a “prohibited transaction” (as such term is defined in Section 406 of ERISA or Section 4975 of the Code), and (B) such designation, funding and maintenance would not result in any interest requiring registration under the Securities Act of 1933, as amended, or qualification under any state securities law, and shall from time to time provide to the Borrower the tax and other forms required pursuant to Section 2.8(e) hereof with respect to such SPC as though such SPC were a Lender hereunder. In no event shall the Borrower or any Lender other than the Granting Lender be obligated hereunder to pay any additional amounts under any provision of this Agreement (pursuant to Article 10 hereof or otherwise) by reason of a Granting Lender’s designation of an SPC or the funding or maintenance of Advances by such SPC, in excess of amounts which the Borrower would have been obligated to pay if such Granting Lender had not made such designation and such Granting Lender were itself funding and maintaining such Advances. The Administrative Agent shall register the interest of any SPC in an Advance from time to time on the Register maintained pursuant to Section 11.5(g) hereof.

Section 11.6 Accounting Principles. All references in this Agreement to GAAP shall be to such principles as in effect from time to time. All accounting terms used herein without definition shall be used as defined under GAAP. All references to the financial statements of the Borrower and to Adjusted EBITDA, Total Debt, Interest Expense, Consolidated Tangible Assets, Consolidated Total Assets and other such terms shall be deemed to refer to such items of the Credit Parties, on a fully consolidated basis. The Borrower shall deliver to the Lenders at the same time as the delivery of any quarterly or annual financial statements required pursuant to Section 6.1 or 6.2 hereof, as applicable, (a) a description in reasonable detail of any material variation between the application of GAAP employed in the preparation of such statements and the application of GAAP employed in the preparation of the next preceding quarterly or annual financial statements, as applicable, and (b) reasonable estimates of the differences between such statements arising as a consequence thereof. If, within thirty (30) days after the delivery of the quarterly or annual financial statements referred to in the immediately preceding sentence, the Majority Lenders shall object in writing to the Borrower’s determining compliance hereunder on such basis, (1) calculations for purposes of determining compliance hereunder shall be made on a basis consistent with those used in the preparation of the latest financial statements as to which such objection shall not have been made, or (2) if requested by the Borrower, the Majority Lenders will negotiate in good faith to amend the covenants herein to give effect to the changes in GAAP in a manner consistent with this Agreement (and so long as the Borrower complies in good faith with the provisions of this Section 11.6, no Default or Event of Default shall occur hereunder solely as a result of such changes in GAAP).

Section 11.7 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such separate counterparts shall together constitute one and the same instrument.

Section 11.8 Governing Law. This Agreement and the Notes shall be construed in accordance with and governed by the internal laws of the State of New York applicable to agreements made and to be performed the State of New York. If any action or proceeding shall be brought by the Administrative Agent or any Lender hereunder or under any other Loan Document in order to enforce any right or remedy under this Agreement or under any Note or

any other Loan Document, the Borrower hereby consents and will cause each Restricted Subsidiary to, submit to the jurisdiction of any state or federal court of competent jurisdiction sitting within the area comprising the Southern District of New York on the date of this Agreement. The Borrower, for itself and on behalf of its Restricted Subsidiaries, hereby agrees that, to the extent permitted by Applicable Law, service of the summons and complaint and all other process which may be served in any such suit, action or proceeding may be effected by mailing by registered mail a copy of such process to the offices of the Borrower at the address given in Section 11.1 hereof and that personal service of process shall not be required. Nothing herein shall be construed to prohibit service of process by any other method permitted by law, or the bringing of any suit, action or proceeding in any other jurisdiction.

Section 11.9 Severability. To the extent permitted by law, any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof in that jurisdiction or affecting the validity or enforceability of such provision in any other jurisdiction.

Section 11.10 Interest.

(a) In no event shall the amount of interest due or payable hereunder or under the Notes exceed the maximum rate of interest allowed by Applicable Law, and in the event any such payment is inadvertently made by the Borrower or inadvertently received by the Administrative Agent or any Lender, then such excess sum shall be credited as a payment of principal, unless, if no Event of Default shall have occurred and be continuing, the Borrower shall notify the Administrative Agent or such Lender, in writing, that it elects to have such excess sum returned forthwith. It is the express intent hereof that the Borrower not pay and the Administrative Agent and the Lenders not receive, directly or indirectly in any manner whatsoever, interest in excess of that which may legally be paid by the Borrower under Applicable Law.

(b) Notwithstanding the use by the Lenders of the Base Rate and the LIBOR as reference rates for the determination of interest on the Loans, the Lenders shall be under no obligation to obtain funds from any particular source in order to charge interest to the Borrower at interest rates related to such reference rates.

Section 11.11 Table of Contents and Headings. The Table of Contents and the headings of the various subdivisions used in this Agreement are for convenience only and shall not in any way modify or amend any of the terms or provisions hereof, nor be used in connection with the interpretation of any provision hereof.

(c) In connection with any proposed amendment, modification, waiver or termination (a “Proposed Change”) requiring the consent of all Lenders, if the consent of Majority Lenders is obtained, but the consent of the other Lenders whose consent is required is not obtained (any such Lender whose consent is not obtained being referred to as a “Non-Consenting Lender”), then at the Borrower’s request (and at the Borrower’s sole cost and expense) a Replacement Lender selected by the Borrower and reasonably acceptable to the Administrative Agent, shall have the right to purchase from such Non-Consenting Lenders, and such Non-Consenting Lenders agree that they shall, upon the Borrower’s request, sell and assign to such Person, all of the DDTL Commitments and/or Revolving Loan Commitments and/or Incremental Facility Commitments and all outstanding Loans of such Non-Consenting Lenders for an amount equal to the principal balance of all Loans held by the Non-Consenting Lenders and all accrued interest and fees and other amounts due or outstanding to such Non-Consenting Lender through the date of sale, such purchase and sale to be consummated pursuant to an executed Assignment and Assumption Agreement substantially in the form on Exhibit S attached hereto.

EXHIBIT A

TO LOAN AGREEMENT

FORM OF BORROWER PLEDGE AGREEMENT

THIS BORROWER PLEDGE AGREEMENT (this “Agreement”) is entered into as of the              day of                     , 2005, by and among SPECTRASITE COMMUNICATIONS, INC., a Delaware corporation (the “Pledgor”), and TORONTO DOMINION (TEXAS) LLC, as administrative agent (the “Administrative Agent”) for itself and on behalf of the Secured Parties defined below. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned thereto in the Loan Agreement.

W I T N E S S E T H:

WHEREAS, the Pledgor, in its capacity as Borrower (as defined therein), the Lenders (as defined therein), the Issuing Bank (as defined therein), the Syndication Agent (as defined therein) and the Administrative Agent (collectively with the Lenders, the Issuing Bank and the Syndication Agent, the “Secured Parties”), are all parties to that certain Loan Agreement dated as of October 27, 2005 (as amended, modified, restated or supplemented from time to time, the “Loan Agreement”); and

WHEREAS, pursuant to the terms of the Loan Agreement, the Pledgor executed that certain Borrower Guaranty dated as of                     , 2005 (the “Guaranty”) and, as a condition precedent to the effectiveness of the Loan Agreement, the Pledgor is required to execute and deliver this Agreement; and

WHEREAS, to secure the payment of all Obligations of the Pledgor under the Loan Agreement to the extent that it directly receives proceeds from any Advance thereunder and the Guarantied Obligations (as defined in the Guaranty) (the “Secured Obligations”), the Pledgor and the Administrative Agent (on behalf of the Secured Parties), have agreed that the Ownership Interests owned by the Pledgor listed on Schedule 1 attached hereto shall be pledged by the Pledgor to the Secured Parties to secure the Secured Obligations;

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Warranty. The Pledgor hereby represents and warrants to the Secured Parties that (a) except for the security interest created hereby, the Pledgor owns the Pledged Interests (which constitute the percentage of the issued and outstanding Ownership Interests of the Subsidiaries as set forth on Schedule 1 attached hereto), free and clear of all Liens (except Permitted Liens), (b) the shares of Capital Stock pledged hereunder are duly issued, fully paid and non-assessable, and (c) the Pledgor has the unencumbered right to pledge the Pledged Interests. In addition, the Pledgor represents and covenants as follows: (1) the Pledged Interests represent (a) subject to Section 5.10 of the Loan Agreement, all of the Pledgor’s Ownership Interests in any direct wholly-owned Domestic Subsidiary of the Pledgor and (b) not less than sixty-five percent (65%)

of the Pledgor’s Ownership Interests in any direct wholly-owned Foreign Subsidiary of the Pledgor; and (2) upon possession and retention of the certificates evidencing Pledged Interests that are “securities” within the meaning of Article 8 of the Uniform Commercial Code (“UCC”) (such Pledged Interests hereinafter referred to as “Certificated Ownership Interests”) by the Administrative Agent, the Secured Parties shall have a valid and perfected first priority security interest in the Certificated Ownership Interests (other than Permitted Liens having priority) securing the payment of the Secured Obligations.

2. Security Interest. The Pledgor hereby unconditionally grants and assigns to the Secured Parties, and their respective successors and permitted assigns, a continuing security interest in and security title to (a) the Ownership Interests set forth on Schedule 1 attached hereto, (b) subject to Section 5.10 of the Loan Agreement, the Ownership Interests in any Domestic Subsidiary of the Pledgor acquired by such Pledgor after the Agreement Date, and in each case, all certificates representing such Ownership Interests, all rights, options, warrants, stock or other securities or other property which may hereafter be received, receivable or distributed in respect of such Ownership Interests, together with all proceeds of the foregoing, including, without limitation, all dividends, cash, notes, securities or other property from time to time acquired, receivable or otherwise distributed in respect of, or in exchange for, the foregoing, all of which shall constitute “Pledged Interests” hereunder. The Pledgor has delivered to the Administrative Agent all of its right, title and interest in and to the Pledged Interests, together with certificates with respect to Certificated Ownership Interests, and undated stock powers endorsed in blank with respect to Certificated Ownership Interests, as security for the Secured Obligations; it being the intention of the parties hereto that beneficial ownership of the Pledged Interests, including, without limitation, all voting, consensual and dividend rights, shall remain in the Pledgor until the occurrence and during the continuance of an Event of Default and until the Administrative Agent shall notify such Pledgor of the Administrative Agent’s exercise of voting and dividend rights to the Pledged Interests pursuant to Section 9 hereof.

3. Additional Pledged Interests. In the event that, during the term of this Agreement:

(a) any stock dividend, stock split, reclassification, readjustment, or other change is declared or made in the capital structure of any Subsidiary of the Pledgor, or any new Ownership Interests are issued by any Subsidiary of the Pledgor, or any new Subsidiary of the Pledgor is formed or acquired, all new, substituted, and additional Ownership Interests shall be issued to the Pledgor and shall be promptly delivered to the Administrative Agent, together with undated stock powers endorsed in blank by the Pledgor with respect to Certificated Ownership Interests, and shall thereupon constitute Pledged Interests to be held by the Administrative Agent under the terms of this Agreement; and

(b) any subscriptions, warrants or any other rights or options shall be issued in connection with the Ownership Interests consisting of shares of Capital Stock, all new stock or other securities acquired through such subscriptions, warrants, rights or options by the Pledgor shall be promptly delivered to the Administrative Agent, together with undated stock powers endorsed in blank, and shall thereupon constitute Pledged Interests to be held by the Administrative Agent under the terms of this Agreement.

- 2 -

Notwithstanding the foregoing, under this Section 3, the Pledgor shall not be required to pledge or deliver Ownership Interests in any Subsidiary of such Pledgor if an express or deemed pledge of such Ownership Interests (including through pledges of Ownership Interests in Restricted Subsidiaries that are treated as flow-through or fiscally transparent entities for U.S. Federal income tax purposes) shall result in a Tax Impediment, as reasonably determined by the Pledgor.

4. Default. In the event of the occurrence of an Event of Default and so long as any such Event of Default is continuing, the Secured Parties may sell or otherwise dispose of the Pledged Interests at a public or private sale or make other commercially reasonable disposition of the Pledged Interests or any portion thereof after fifteen (15) days’ notice to the the Pledgor, and the Secured Parties, or any of them, may purchase the Pledged Interests or any portion thereof at any public sale. The proceeds of the public or private sale or other disposition shall be applied first to the costs of the Administrative Agent incurred in connection with the sale, expressly including, without limitation, any costs under Section 7 hereof, and then to the Secured Obligations as provided in the Loan Agreement. In the event the proceeds of the sale or other disposition of the Pledged Interests are insufficient to satisfy the Secured Obligations, the Pledgor shall remain liable for any such deficiency. The Pledgor waives, to the extent permitted by Applicable Law, the rights of equity of redemption, appraisal, notice of acceptance, presentment, demand and marshalling, to the extent applicable.

5. Additional Rights of Secured Parties. In addition to its rights and privileges under this Agreement, the Secured Parties shall have all the rights, powers and privileges of a secured party under the UCC as in effect in any applicable jurisdiction and other Applicable Law.

6. Return of Pledged Interests to the Pledgor. Upon payment in full of all Obligations under the Loan Agreement and the other Loan Documents, and satisfaction in full of any other Secured Obligations, other than the Secured Obligations which survive the termination of the Loan Agreement as provided in Section 11.16 of the Loan Agreement, and after such time as the Lenders shall have no obligation to make any further Advances (including, without limitation, with respect to Letters of Credit or draws thereon) to the Borrower, in its capacity as Pledgor, or as otherwise set forth in the Loan Agreement (including, without limitation, Section 5.11 thereof), this Agreement shall terminate and the Administrative Agent shall return the remaining Pledged Interests and all rights received by the Administrative Agent as a result of its possessory interest in the Pledged Interests to the the Pledgor.

7. Disposition of Pledged Interests by Administrative Agent. The Pledged Interests are not registered or qualified under the various federal or state securities laws of the United States and disposition thereof after an Event of Default may be restricted to one or more private (instead of public) sales in view of the lack of such registration. The Pledgor understands that upon such disposition, the Secured Parties may approach only a restricted number of potential purchasers and further understands that a sale under such circumstances may yield a lower price for the Pledged Interests than if the Pledged Interests were registered and qualified pursuant to federal and state securities laws and sold on the open market. The Pledgor, therefore, agrees that:

(a) if the Secured Parties shall, pursuant to the terms of this Agreement, sell or cause the Pledged Interests or any portion thereof to be sold at a private sale, the Secured

- 3 -

Parties shall have the right to rely upon the advice and opinion of any national brokerage or investment firm having recognized expertise and experience in connection with shares of communications tower companies (but shall not be obligated to seek such advice and the failure to do so shall not be considered in determining the commercial reasonableness of such action) as to the best manner in which to dispose of the Pledged Interests for sale and as to the best price reasonably obtainable at the private sale thereof; and

(b) that such reliance shall be conclusive evidence that the Secured Parties have handled such disposition in a commercially reasonable manner absent manifest error.

8. Pledgor’s Obligations Absolute. The obligations of the Pledgor under this Agreement shall be direct and immediate and not conditional or contingent upon the pursuit of any remedies against the Pledgor or any other Person, nor against other security or liens available to any Secured Party. The Pledgor hereby waives any right to require that an action be brought against any other Person or to require that resort be had to any other security or to any balance of any deposit account or credit on the books of any of the Secured Parties in favor of any other Person prior to the exercise of remedies hereunder, or to require action hereunder prior to resort by the Administrative Agent to any other security or collateral for the Secured Obligations.

8. Remedies. Upon the occurrence and during the continuation of an Event of Default, the Secured Parties shall have such rights and remedies as are set forth in the Loan Agreement, the other Loan Documents and herein, all the rights, powers and privileges of a secured party under the UCC of the State of New York and any other applicable jurisdiction, and all other rights and remedies available to the Secured Parties, or any of them, at law or in equity.

and enjoy the full rights and benefits granted to the Administrative Agent under this Agreement and the other Loan Documents. Without limiting the generality of the foregoing, the Borrower shall, at the Borrower’s cost and expense, use its reasonable best efforts to assist in obtaining all approvals of the FCC which are then required by law for or in connection with any action or transaction contemplated by this Agreement or Article 9 of the UCC as in effect in any applicable jurisdiction, and, at the Administrative Agent’s request, prepare, sign and file with the FCC the assignor’s or transferor’s portion of any application or applications for consent to the assignment of the Licenses or transfer of control thereof necessary or appropriate under the FCC’s rules for approval of any sale or transfer of the Licenses in connection with the Administrative Agent’s exercise of remedies under this Agreement. The Administrative Agent shall have the right, in connection with the issuance of any order for relief in a bankruptcy proceeding, to petition the bankruptcy court for the transfer of control or assignment of the Collateral to a receiver, trustee, transferee, or similar official or to any purchaser of the Collateral pursuant to any public or private sale, foreclosure or other exercise of remedies available to the Administrative Agent, all as permitted by Applicable Law. All amounts realized or collected through the exercise of remedies hereunder shall be applied to the Secured Obligations as provided in the Loan Agreement.

9. Notification of Account Debtors. Upon the occurrence and during the continuation of an Event of Default, the Administrative Agent may notify the account debtors that all payments with respect to Accounts of the Borrower are to be paid directly to the Administrative Agent and any amount thereafter paid to the Borrower shall be received in trust by the Borrower for the benefit of the Administrative Agent and segregated from other funds of the Borrower and paid over to the Administrative Agent in the form received (together with any necessary endorsements).

10. Remedies of Administrative Agent. Upon the occurrence and during the continuation of an Event of Default, and after written notice to the Borrower, the Administrative Agent or its designee may proceed to perform any and all of the obligations of the Borrower contained in any of the Contracts, Other Contracts or Leases and exercise any and all rights of the Borrower therein contained as fully as the Borrower itself could. The Borrower hereby appoints the Administrative Agent its attorney-in-fact, with power of substitution, to take such action, execute such documents, and perform such work after the occurrence and during the continuation of an Event of Default as the Administrative Agent may deem appropriate in exercise of the rights and remedies granted the Secured Parties, or any of them, herein or in any other Loan Document following written notice to the Borrower. The power of attorney granted herein is coupled with an interest and shall be irrevocable.

11. Additional Remedies. Upon the occurrence and during the continuation of an Event of Default, should the Borrower fail to perform or observe any covenant or comply with any condition contained in any of the Contracts, the Other Contracts or the Leases, then following written notice to the Borrower, the Administrative Agent may, but without obligation to do so and without releasing any the Borrower from its obligation to do so, and after written notice to the Borrower, perform such covenant or condition and, to the extent that the Administrative Agent shall incur any reasonable costs or pay any expenses in connection therewith, including any reasonable costs or expenses of litigation associated therewith, such costs, expenses or payments shall be included in the Secured Obligations secured hereby and

- 6 -

shall bear interest from the payment of such costs or expenses by the Administrative Agent at the Default Rate. None of the Secured Parties shall be obliged to perform or discharge any obligation of the Borrower under any of the Contracts, the Other Contracts or the Leases.

12. Administrative Agent May Collect Accounts. The Borrower hereby further appoints the Administrative Agent, effective upon the occurrence and during continuation of an Event of Default as its attorney-in-fact, with power of substitution, with authority to collect all Accounts, to endorse the name of the Borrower on any note, acceptance, check, draft, money order or other evidence of debt or of payment which constitutes a portion of the Collateral and which may come into the possession of the Secured Parties, or any of them, and generally to do such other things and acts in the name the Borrower with respect to the Collateral as are necessary or appropriate to protect or enforce the rights hereunder of the Secured Parties. The Borrower further authorizes the Administrative Agent, effective upon the occurrence and during the continuation of an Event of Default, to compromise and settle or to sell, assign or transfer or to ask, collect, receive or issue any and all claims possessed by the Borrower which constitute a portion of the Collateral, all in the name of the Borrower. After deducting all reasonable expenses and charges (including the Administrative Agent’s attorneys’ fees) of retaking, keeping, storing and selling the Collateral, the Administrative Agent may apply the proceeds in payment of any of the Secured Obligations in the order of application set forth in the Loan Agreement. The power of attorney granted herein is coupled with an interest and shall be irrevocable. The Borrower agrees that if steps are taken by the Administrative Agent to enforce its rights hereunder, or to realize upon any of the Collateral, the Borrower shall pay to the Administrative Agent the amount of the Administrative Agent’s reasonable costs, including attorneys’ fees, and the Borrower’s obligation to pay such amounts shall be deemed to be a part of the Secured Obligations secured hereunder. Upon the occurrence and during the continuation of an Event of Default, the Borrower shall segregate all proceeds of any Collateral from the other assets of the Borrower.

13. Indemnification. The Borrower shall indemnify and hold harmless the Secured Parties, and any other Person acting hereunder for all losses, costs, damages, fees and expenses whatsoever associated with the exercise of the powers of attorney granted herein and shall release each Secured Party, and any other Person acting hereunder from all liability whatsoever for the exercise of the foregoing powers of attorney and all actions taken pursuant thereto, except, in either event, in the case of bad faith, gross negligence or willful misconduct by the Person seeking indemnification.

14. Remedies Cumulative. The Borrower agrees that the rights of the Secured Parties, or any of them, under this Agreement, the Loan Agreement, any other Loan Document or any other contract or agreement now or hereafter in existence among the Secured Parties and the Borrower or any Subsidiary of the Borrower and the other obligors thereunder, or any of them, shall be cumulative, and that each Secured Party may from time to time exercise such rights and such remedies as such Person or Persons may have thereunder and under the laws of the United States or any state, as applicable, in the manner and at the time that such Person or Persons in its or their sole discretion desire, subject to the terms of such agreements. The Borrower further expressly agrees that the Secured Parties shall in no event be under any obligation to resort to any Collateral secured hereby prior to exercising any other rights that the Secured Parties, or any of them, may have against the Borrower or any Subsidiary of the

- 7 -

Borrower or any of its respective properties, nor shall the Secured Parties, or any of them, be obliged to resort to any other collateral or security for the Secured Obligations, other than the Collateral, prior to any exercise of the Administrative Agent’s rights against any of the Borrower and its property hereunder.

15. Obligations Commercial in Nature. The Borrower hereby acknowledges that the Obligations arose out of a commercial transaction, and agrees that if an Event of Default shall occur and be continuing, the Administrative Agent shall, to the extent permitted by Applicable Law, have the right to immediate possession without notice or a hearing, and hereby knowingly and intelligently waives, to the extent permitted by Applicable Law, any and all rights it may have to any notice and posting of a bond by the Secured Parties, or any of them, prior to seizure by the Administrative Agent or any of its transferees, assigns or successors in interest, of the Collateral or any portion thereof.

A waiver by the Secured Parties, or any of them, of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion.

(i) Revolving Loans and AMT Letter of Credit Obligations in Excess of Revolving Loan Commitments. If, at any time, the amount of the sum of the Revolving Loans and AMT Letter of Credit Obligations (or, if applicable, the Incremental Facility Loans) shall exceed the Revolving Loan Commitments (or, if applicable, the Incremental Facility Commitments), the Borrowers shall, on such date and subject to Section 2.9 hereof, make a repayment of the principal amount of the Revolving Loans (or, if applicable, the Incremental Facility Loans), or, if there are no such Loans then outstanding, establish, if applicable, a Letter of Credit Reserve Account, in each case, in an amount equal to such excess, together with any accrued interest and fees with respect thereto.

(ii) Unreinvested Net Proceeds from Asset Sales and Insurance and Condemnation Proceedings. At any time after the aggregate Unreinvested Net Proceeds from all sales, transfers or other dispositions of assets of the Credit Parties or from any insurance or condemnation proceeding in respect of such assets after the Agreement Date exceeds $10,000,000.00, the Loans shall be repaid in an amount equal to, in the aggregate, such Unreinvested Net Proceeds. The amount of the Unreinvested Net Proceeds required to be repaid under this Section 2.6(b)(ii) shall be applied first, to any Term Loan A Loans, DDT Loans, SSI Term Loan A Loans and SSI DDT Loans then outstanding, on a pro rata basis, second, once the outstanding Term Loan A Loans, DDT Loans, SSI Term Loan A Loans and SSI DDT Loans are paid in full, to any Revolving Loans and SSI Revolving Loans then outstanding, on a pro rata basis (without a reduction in the Revolving Loan Commitments or SSI Revolving Loan Commitments) and third, once the outstanding Revolving Loans and SSI Revolving Loans are paid in full, as a reduction of the DDTL Commitments and SSI DDTL Commitments, on a pro rata basis. Accrued interest on the principal amount of the Loans being repaid pursuant to this Section 2.6(b)(ii) to the date of such repayment will be paid by the Borrowers concurrently with such principal repayment.

(iii) Maturity Date. A final payment of all Loans, together with accrued interest and fees with respect thereto, shall be due and payable on the Maturity Date.

(iv) SSI Revolving Loans and SSI Letter of Credit Obligations in Excess of SSI Revolving Loan Commitments. If, at any time, the amount of the sum of the SSI Revolving Loans and SSI Letter of Credit Obligations (or, if applicable, the Incremental Facility Loans) shall exceed the SSI Revolving Loan Commitments (or, if applicable, the Incremental Facility Commitments), the Borrowers

11

shall, on such date and subject to Section 2.9 hereof, make a repayment of the principal amount of the SSI Revolving Loans (or, if applicable, the Incremental Facility Loans), or, if there are no such Loans then outstanding, establish, if applicable, a Letter of Credit Reserve Account, in each case, in an amount equal to such excess, together with any accrued interest and fees with respect thereto.”

(v) Article 2, Loans, of the AMT Loan Agreement is hereby further amended by deleting clause (a) of Section 2.7, Notes; Loan Accounts, in its entirety and substituting the following therefor:

“(a) The Loans shall be repayable in accordance with the terms and provisions set forth herein and, if requested, shall be evidenced by the Notes. Each Note shall be issued on a joint and several basis by the Borrowers upon the request of any Lender in connection with the Commitments or Loans held by it and shall be duly executed and delivered by one or more Authorized Signatories.”

(vi) Article 2, Loans, of the AMT Loan Agreement is hereby further amended by deleting Section 2.10, Prepayments and Repayments, in its entirety and substituting the following therefor:

“Section 2.10 Pro Rata Treatment.

(a) Advances. Each Advance under the Revolving Loan Commitments from the Lenders hereunder shall be made pro rata on the basis of the applicable Commitment Ratios of the Lenders having a Revolving Loan Commitment. Each Advance under the DDTL Commitments from the Lenders hereunder shall be made on a pro rata basis of the applicable Commitment Ratios of the Lenders having DDTL Commitments. Each Advance under the SSI Revolving Loan Commitments from the Lenders hereunder shall be made pro rata on the basis of the applicable Commitment Ratios of the Lenders having an SSI Revolving Loan Commitment. Each Advance under the SSI DDTL Commitments from the Lenders hereunder shall be made on a pro rata basis of the applicable Commitment Ratios of the Lenders having SSI DDTL Commitments.

(b) Payments.

If any Lender shall obtain any payment (whether involuntary, through the exercise of any right of set-off, or otherwise) on account of the Loans in excess of its ratable share of the Loans under its applicable Commitment Ratio, such Lender shall forthwith purchase from the other Lenders such participations in the portion of the applicable Loans made by them as shall be necessary to cause such purchasing Lender to share the excess payment ratably with each of them; provided, however, that if all or any portion of such excess payment is thereafter recovered from such purchasing Lender, such purchase from each Lender shall be rescinded and each such other Lender shall repay to the purchasing Lender the purchase price to the extent of such recovery.

12

The Borrowers agree that any Lender so purchasing a participation from another Lender pursuant to this Section 2.10(b) may, to the fullest extent permitted by law, exercise all its rights of payment (including, without limitation, the right of set-off) with respect to such participation as fully as if such purchasing Lender were the direct creditor of the Borrowers in the amount of such participation.

(c) Commitment Reductions. Any reduction of the Revolving Loan Commitments required or permitted hereunder shall reduce the Revolving Loan Commitment of each Lender having a Revolving Loan Commitment on a pro rata basis based on the Commitment Ratio of such Lender for the Revolving Loan Commitment. Any reduction of the DDTL Commitments required or permitted hereunder shall reduce the DDTL Commitment of each Lender having a DDTL Commitment on a pro rata basis based on the Commitment Ratio of such Lender for the DDTL Commitment.

Any reduction of the SSI Revolving Loan Commitments required or permitted hereunder shall reduce the SSI Revolving Loan Commitment of each Lender having an SSI Revolving Loan Commitment on a pro rata basis based on the Commitment Ratio of such Lender for the SSI Revolving Loan Commitment.

(vii) Article 2, Loans, of the AMT Loan Agreement is hereby further amended by deleting clauses (a), (d), (f), (g) and (h) of Section 2.13, Letters of Credit, in its entirety and substituting the following therefor:

“Section 2.13 Letters of Credit.

(a) Subject to the terms and conditions hereof, the Issuing Bank, on behalf of the Lenders having a Revolving Loan Commitment and the Lenders having an SSI Revolving Loan Commitment, and in reliance on the agreements of such Lenders set forth in Section 2.13(d) hereof, hereby agrees to issue one or more Letters of Credit (1) in respect of Lenders having Revolving Loan Commitments up to an aggregate face amount equal to the Available Letter of Credit Commitment and (2) in respect of Lenders having SSI Revolving Loan Commitments up to an aggregate face amount equal to the Available SSI Letter of Credit Commitment, in each case determined immediately prior to giving effect to the issuance thereof; provided, however, that the Issuing Bank shall not issue any Letter of Credit (i) unless the conditions precedent to the issuance thereof set forth in Section 3.3 hereof have been satisfied, (ii) if any Default then exists or would be caused thereby, (iii) if, after giving effect to such issuance, the Available Revolving Loan Commitment (or, if applicable, the SSI Letter of Credit Commitment) would be less than zero or (iv) within thirty (30) days preceding the Maturity Date. Each Letter of Credit shall (A) be payable at sight, (B) be denominated in United States

13

dollars, (C) expire, (i) with respect to Standby Letters of Credit, no later than the earlier to occur of (x) the fifth Business Day preceding the Maturity Date and (y) 360 days after its date of issuance (but may contain provisions for automatic renewal; provided that no Default or Event of Default exists on the renewal date or would be caused by such renewal), and (ii) with respect to Commercial Letters of Credit, no later than the earlier to occur of (x) the thirtieth day preceding the Maturity Date and (y) 180 days after its date of Issuance (but may contain provisions for automatic renewal; provided that no Default or Event of Default exists on the renewal date or would be caused by such renewal). Each Letter of Credit shall be subject to the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500 and, to the extent not inconsistent therewith, the laws of the State of New York. The Issuing Bank shall not at any time be obligated to issue, or cause to be issued, any Letter of Credit if such issuance would conflict with, or cause the Issuing Bank to exceed any limits imposed by, any Applicable Law. If a Letter of Credit provides that it is automatically renewable unless notice is given by the Issuing Bank that it will not be renewed, the Issuing Bank shall not be bound to give a notice of non-renewal unless directed to do so by Lenders having in the aggregate more than fifty percent (50%) of the Revolving Loan Commitment (or, if applicable, the SSI Revolving Loan Commitment) at least sixty-five (65) days prior to the then scheduled expiration date of such Letter of Credit. It is hereby agreed that the Letters of Credit set forth on Schedule 2 attached to the Assumption Agreement [to contain a list of all outstanding Letters of Credit on the Combination Date] are Letters of Credit issued hereunder for all purposes hereunder notwithstanding anything herein that may be construed to the contrary.

(d) The Borrowers hereby agree to immediately reimburse the Issuing Bank for amounts paid by the Issuing Bank in respect of draws under a Letter of Credit issued at a Borrower’s request. In order to facilitate such repayment, (i) with respect to AMT Letters of Credit, the Borrowers hereby irrevocably request the Lenders having a Revolving Loan Commitment, and such Lenders hereby severally agree, on the terms and conditions of this Agreement (other than as provided in Article 2 hereof with respect to the amounts of, the timing of requests for, and the repayment of Advances hereunder and in Article 3 hereof with respect to conditions precedent to Advances hereunder), with respect to any honoring of any draw under an AMT Letter of Credit prior to the occurrence of an Event of Default under Section 8.1(f) or (g) hereof, to make an Advance (which Advance may be a LIBOR Advance if the Borrowers so request in a timely manner or may be Converted to a LIBOR Advance as provided in the Loan Agreement) to the Borrowers on each day on which the Issuing Bank honors a draw is made under any Letter of Credit and in the amount of such draw, and to pay the proceeds of such Advance directly to the Issuing Bank to reimburse the Issuing Bank for the amount paid by it upon such draw and (ii) with respect to SSI Letters of Credit, the Borrowers hereby irrevocably request the Lenders having an SSI Revolving Loan Commitment, and such Lenders hereby severally agree, on the terms and conditions of this Agreement (other than as provided in Article 2 hereof with respect to the amounts of, the timing of requests for, and the repayment of Advances hereunder and in Article 3 hereof with respect to conditions precedent to Advances hereunder), with respect to any honoring of any draw under an SSI Letter of Credit prior to the occurrence of an Event of

14

Default under Section 8.1(f) or (g) hereof, to make an Advance (which Advance may be a LIBOR Advance if the Borrowers so request in a timely manner or may be Converted to a LIBOR Advance as provided in the Loan Agreement) to the Borrowers on each day on which the Issuing Bank honors a draw is made under any SSI Letter of Credit and in the amount of such draw, and to pay the proceeds of such Advance directly to the Issuing Bank to reimburse the Issuing Bank for the amount paid by it upon such draw. Each Lender having a Revolving Loan Commitment shall pay its share of the Advance referred to in clause (ii) of the second preceding sentence by paying its portion of such Advance to the Administrative Agent in accordance with Section 2.2(e) hereof and its respective Commitment Ratio under the Revolving Loan Commitments, without reduction for any set off or counterclaim of any nature whatsoever and regardless of whether any Default or Event of Default (other than with respect to an Event of Default under Section 8.1(f) or (g) hereof) then exists or would be caused thereby. Each Lender having an SSI Revolving Loan Commitment shall pay its share of the Advance referred to in clause (i) of the preceding sentence above by paying its portion of such Advance to the Administrative Agent in accordance with Section 2.2(e) hereof and its respective Commitment Ratio under the SSI Revolving Loan Commitments, without reduction for any set off or counterclaim of any nature whatsoever and regardless of whether any Default or Event of Default (other than with respect to an Event of Default under Section 8.1(f) or (g) hereof) then exists or would be caused thereby. If at any time that any AMT Letters of Credit are outstanding, any of the events described in clauses of Section 8.1(f) or (g) hereof shall have occurred and be continuing, then each Lender having a Revolving Loan Commitment shall, automatically upon the occurrence of any such event and without any action on the part of the Issuing Bank, the Borrowers, the Administrative Agent or such Lenders, be deemed to have purchased an undivided participation in the face amount of all AMT Letters of Credit then outstanding in an amount equal to such Lender’s respective Commitment Ratio under the Revolving Loan Commitments, and each Lender having a Revolving Loan Commitment shall, notwithstanding such Event of Default, upon a drawing being honored under any AMT Letter of Credit, immediately pay to the Administrative Agent for the account of the Issuing Bank, in immediately available funds, the amount of such Lender’s participation (and the Issuing Bank shall deliver to such Lender a loan participation certificate dated the date of the occurrence of such event and in the amount of such Lender’s respective Commitment Ratio under the Revolving Loan Commitments). If at any time that any SSI Letters of Credit are outstanding, any of the events described in clauses of Section 8.1(f) or (g) hereof shall have occurred and be continuing, then each Lender having an SSI Revolving Loan Commitment shall, automatically upon the occurrence of any such event and without any action on the part of the Issuing Bank, the Borrowers, the Administrative Agent or such Lenders, be deemed to have purchased an undivided participation in the face amount of all SSI Letters of Credit then outstanding in an amount equal to such Lender’s respective Commitment Ratio under the SSI Revolving Loan Commitments, and each Lender having an SSI Revolving Loan Commitment shall, notwithstanding such Event of Default, upon a drawing being honored under any SSI Letter of Credit, immediately pay to the Administrative Agent for the account of the Issuing Bank, in immediately available funds, the amount of such Lender’s participation (and the Issuing Bank shall deliver to such Lender a loan participation certificate dated the date of the occurrence of such event

15

and in the amount of such Lender’s respective Commitment Ratio under the SSI Revolving Loan Commitments). The disbursement of funds in connection with a draw under a Letter of Credit pursuant to this Section 2.13(d) shall be subject to the terms and conditions of Section 2.2(e) hereof. The obligation of each Lender having a Revolving Loan Commitment or SSI Revolving Loan Commitment to make payments to the Administrative Agent, for the account of the Issuing Bank, in accordance with this Section 2.13 shall be absolute and unconditional and no such Lender shall be relieved of its obligations to make such payments by reason of non-compliance by any other Person with the terms of the Letter of Credit or for any other reason. The Administrative Agent shall promptly remit to the Issuing Bank the amounts so received from the other Lenders. Any overdue amounts payable by the Lenders having a Revolving Loan Commitment or an SSI Revolving Loan Commitment to the Issuing Bank in respect of a draw under any Letter of Credit shall bear interest, payable on demand, at the rate on overnight Federal funds transactions with members of the Federal Reserve System arranged by Federal funds brokers, as published for such day by the Federal Reserve Bank of New York.

(f) If any change in Applicable Law, any change in the interpretation or administration thereof, or any change in compliance with Applicable Law by the Issuing Bank or any Lender having a Revolving Loan Commitment or an SSI Revolving Loan Commitment as a result of any official request or directive of any governmental authority, central bank or comparable agency (whether or not having the force of law) shall (i) impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System), special deposit, capital adequacy, assessment or other requirements or conditions against Letters of Credit issued by the Issuing Bank or against participations by any other Lender in the Letters of Credit or (ii) impose on the Issuing Bank or any other Lender any other condition regarding any Letter of Credit or any participation therein (other than with respect to Taxes, which shall be governed exclusively by Section 10.3), and the result of any of the foregoing in the reasonable determination of the Issuing Bank or such Lender, as the case may be, is to increase the cost to the Issuing Bank or such Lender of issuing or maintaining any Letter of Credit or purchasing or maintaining any participation therein, as the case may be, by an amount (which amount shall be reasonably determined) deemed by the Issuing Bank or such Lender to be material, and the designation of a different lending office will not avoid the need for additional compensation (without creating other unreimbursed costs or disadvantage to such Lender), then, on request by the Issuing Bank or such Lender, the Borrower shall pay, within ten (10) days after demand, the Issuing Bank or such Lender, as the case may be, such additional amount or amounts as the Issuing Bank or such Lender, as the case may be, so determines will compensate it on an after-tax basis for such increased costs. A certificate of the Issuing Bank or such Lender setting forth the amount, and in reasonable detail the basis for the Issuing Bank or such Lender’s determination of such amount, to be paid to the Issuing Bank or such Lender by the Borrower as a result of any event referred to in this paragraph shall, absent manifest error, be conclusive.

(g) Each Lender having a Revolving Loan Commitment shall be responsible for its pro rata share (based on such Lender’s respective Commitment

16

Ratio under the Revolving Loan Commitments) of any and all reasonable out-of-pocket costs, expenses (including reasonable legal fees) and disbursements which may be incurred or made by the Issuing Bank in connection with the collection of any amounts due under, the administration of, or the presentation or enforcement of any rights conferred by any Letter of Credit, the Borrowers’ or any guarantor’s obligations to reimburse or otherwise. In the event the Borrowers shall fail to pay such expenses of the Issuing Bank within ten (10) days after demand for payment by the Issuing Bank, each Lender having a Revolving Loan Commitment shall thereupon pay to the Issuing Bank its pro rata share (based on such Lender’s respective Commitment Ratio under the Revolving Loan Commitments) of such expenses within five (5) days from the date of the Issuing Bank’s notice to the Lenders having a Revolving Loan Commitment of the Borrowers’ failure to pay; provided, however, that if the Borrowers or any guarantor shall thereafter pay such expense, the Issuing Bank will repay to each Lender having a Revolving Loan Commitment the amounts received from such Lender hereunder. Each Lender having an SSI Revolving Loan Commitment shall be responsible for its pro rata share (based on such Lender’s respective Commitment Ratio under the SSI Revolving Loan Commitments) of any and all reasonable out-of-pocket costs, expenses (including reasonable legal fees) and disbursements which may be incurred or made by the Issuing Bank in connection with the collection of any amounts due under, the administration of, or the presentation or enforcement of any rights conferred by any SSI Letter of Credit, the Borrowers’ or any guarantor’s obligations to reimburse or otherwise. In the event the Borrowers shall fail to pay such expenses of the Issuing Bank within ten (10) days after demand for payment by the Issuing Bank, each Lender having an SSI Revolving Loan Commitment shall thereupon pay to the Issuing Bank its pro rata share (based on such Lender’s respective Commitment Ratio under the SSI Revolving Loan Commitments) of such expenses within five (5) days from the date of the Issuing Bank’s notice to the Lenders having an SSI Revolving Loan Commitment of the Borrowers’ failure to pay; provided, however, that if the Borrowers or any guarantor shall thereafter pay such expense, the Issuing Bank will repay to each Lender having an SSI Revolving Loan Commitment the amounts received from such Lender hereunder.

(h) The Borrowers agree that each Advance by the Lenders having Revolving Loan Commitments and/or SSI Revolving Loan Commitments to reimburse the Issuing Bank for draws under any Letter of Credit, shall, for all purposes hereunder, be deemed to be an Advance under the Revolving Loan Commitment or the SSI Revolving Loan Commitments, as applicable, to the Borrowers and shall be payable and bear interest in accordance with all other Revolving Loans or SSI Revolving Loans, applicable, to the Borrowers.”

(viii) Article 2, Loans, of the AMT Loan Agreement is hereby further amended by deleting clause (a) of Section 2.14, Incremental Facility Advances, therewith in its entirety and substituting the following therefor:

“Section 2.14 Incremental Facility Advances.

17

(a) Subject to the terms and conditions of this Agreement, the Borrower may request an Incremental Facility Commitment (which may be in the form of a revolver or term loan) on any Business Day; provided, however, that (i) the Borrower may not request any Incremental Facility Commitment or an Incremental Facility Advance after the occurrence and during the continuance of a Default or an Event of Default, including, without limitation, any Default or Event of Default that would result after giving effect to any Incremental Facility Advance and (ii) the aggregate amount of such Incremental Facilities shall not exceed $750,000,000.00 [or such aggregate amount as remains available on the Combination Date under the AMT Loan Agreement and the SSI Loan Agreement].¹ No Incremental Facility Loans shall have a maturity date earlier than the Maturity Date. The decision of any Lender to provide an Incremental Facility Commitment to the Borrower shall be at such Lender’s sole discretion and shall be made in writing. The Incremental Facility Commitment of a Lender providing an Incremental Facility Commitment shall, at the request of such Lender, be evidenced by an Incremental Facility Note. Persons not then Lenders may be included as Lenders holding a portion of such Incremental Facility Commitment with the written approval of the Borrower and the Administrative Agent (such approval not to be unreasonably withheld, delayed, or conditioned). The Incremental Facility Commitments shall be governed by this Agreement and the other Loan Documents and be on terms and conditions no more restrictive than those set forth herein and therein. The terms and conditions in this Section 2.14 may be amended with the consent of the Majority Lenders and the Borrower, except to the extent that a specific Lender’s consent is otherwise required with respect to an issuance by such Lender of any Incremental Facility Commitment.”

2. Obligations Several. Regardless of whether any proposed guarantor or any other Person or Persons is, are or shall become in any other way responsible to the Guarantied Parties, or any of them, for or in respect of the Guarantied Obligations or any part thereof, and regardless of whether or not any Person or Persons now or hereafter responsible to the Guarantied Parties,

3. Guaranty Final. Upon the execution and delivery of this Guaranty to the Administrative Agent, this Guaranty shall be deemed to be finally executed and delivered by the Guarantor and shall not be subject to or affected by any promise or condition affecting or limiting the Guarantor’s liability and no statement, representation, agreement or promise on the part of the Guarantied Parties, the Borrower, or any of them, or any officer, employee or agent thereof, unless contained herein forms any part of this Guaranty or has induced the making hereof or shall be deemed in any way to affect the Guarantor’s liability hereunder.

4. Amendment and Waiver. No alteration or waiver of this Guaranty or of any of its terms, provisions or conditions shall be binding upon the Persons against whom enforcement is sought unless made in writing and signed by an authorized officer of such Person.

- 2 -

waiver, omission of the Guarantied Parties, or any of them, or their failure to proceed promptly or otherwise, or by reason of any action taken or omitted by the Guarantied Parties, or any of them, whether or not such action or failure to act varies or increases the risk of, or affects the rights or remedies of, the Guarantor or by reason of any further dealings among the Borrower and the Guarantied Parties, or any of them, or any other guarantor or surety, and the Guarantor, to the extent permitted by Applicable Law, hereby expressly waives and surrenders any defense to its liability hereunder, or any right of counterclaim or offset of any nature or description which it may have or which may exist based upon, and shall be deemed to have consented to, any of the foregoing acts, omissions, things, agreements or waivers.

This Guaranty shall be binding upon the Guarantor, its successors and permitted assigns and inure to the benefit of such successors and assigns.

11. Remedies Cumulative.

No action by the Guarantied Parties, or any of them, permitted hereunder shall in any way impair or affect this Guaranty.

FORM OF HOLDCO PLEDGE AGREEMENT

THIS HOLDCO PLEDGE AGREEMENT (this “Agreement”) is entered into as of the             day of                             , 2005 by and between SPECTRASITE, LLC, a Delaware limited liability company (the “Pledgor”), and TORONTO DOMINION (TEXAS) LLC, as administrative agent (the “Administrative Agent”) for itself and on behalf of the Secured Parties defined below. Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned thereto in the Loan Agreement (as defined herein).

W I T N E S S E T H:

WHEREAS, SpectraSite Communications, Inc., a Delaware corporation, (the “Borrower”), the Lenders (as defined therein), the Issuing Bank (as defined therein), the Syndication Agent (as defined therein) and the Administrative Agent (collectively with the Lenders, the Issuing Bank and the Syndication Agent, the “Secured Parties”) are all parties to that certain Loan Agreement dated as of even date herewith (as amended, modified, restated or supplemented from time to time, the “Loan Agreement”); and

WHEREAS, the Pledgor is the sole stockholder of the Borrower and, as such, will derive substantial economic benefit from the making of the Loans to the Borrower; and

WHEREAS, the Pledgor has executed that certain Holdco Guaranty dated as of even date herewith pursuant to the Loan Agreement (the “Guaranty”), and as a condition precedent to the effectiveness of the Loan Agreement, the Pledgor is required to execute and deliver this Agreement; and

WHEREAS, to secure the payment by the Borrower of its Obligations arising under the Loan Agreement, the Pledgor and the Administrative Agent (on behalf of the Secured Parties) have agreed that the Ownership Interests owned by the Pledgor in the Borrower, listed on Schedule 1 attached hereto shall be pledged by the Pledgor to the Secured Parties to secure the Guarantied Obligations (as defined in the Guaranty);

NOW, THEREFORE, in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Warranty. The Pledgor hereby represents and warrants to the Secured Parties that (a) except for the security interest created hereby, the Pledgor owns the Pledged Interests free and clear of all Liens (except Permitted Liens), (b) the shares of Capital Stock pledged hereunder are duly issued, fully paid and non-assessable, and (c) the Pledgor has the unencumbered right to pledge the Pledged Interests. In addition, the Pledgor represents and covenants as follows: (1) upon possession and retention of the certificates evidencing Pledged Interests that are “securities” within the meaning of Article 8 of the Uniform Commercial Code (“UCC”) (such Pledged Interests hereinafter referred to as “Certificated Ownership Interests”) by the

Administrative Agent, the Secured Parties shall have a valid and perfected first priority security interest (other than Permitted Liens having priority) in the Pledged Interests and (2) upon the filing of all required UCC financing statements, the Secured Parties shall have a first priority security interest (other than Permitted Liens having priority) in such Pledged Interests, in each case, securing the payment of the Guarantied Obligations.

2. Security Interest. The Pledgor hereby unconditionally grants and assigns to the Secured Parties, and their respective successors and assigns, a continuing security interest in and security title to the Ownership Interests set forth on Schedule 1 attached hereto and all certificates representing such Ownership Interests, all rights, options, warrants, stock or other securities or other property which may hereafter be received, receivable or distributed in respect of such Ownership Interests, together with all proceeds of the foregoing, including, without limitation, all dividends, cash, notes, securities or other property from time to time acquired, receivable or otherwise distributed in respect of, or in exchange for, the foregoing, all of which shall constitute “Pledged Interests” hereunder. The Pledgor has delivered to the Administrative Agent all of its right, title and interest in and to the Pledged Interests, together with certificates with respect to Certificated Ownership Interests, and undated stock powers endorsed in blank with respect to Certificated Ownership Interests, as security for the payment of all of the Guarantied Obligations under this Agreement and the Guaranty and any extensions, renewals or amendments of any of the foregoing, however created, acquired, arising or evidenced, whether direct or indirect, absolute or contingent, now or hereafter existing, or due or to become due; it being the intention of the parties hereto that beneficial ownership of the Pledged Interests, including, without limitation, all voting, consensual and dividend rights, shall remain in the Pledgor until the occurrence and during the continuance of an Event of Default and until the Administrative Agent shall notify the Pledgor of the Administrative Agent’s exercise of voting and dividend rights to the Pledged Interests pursuant to Section 9 hereof.

3. Additional Pledged Interests. In the event that, during the term of this Agreement:

(a) any stock dividend, stock split, reclassification, readjustment, or other change is declared or made in the capital structure of the Borrower, or any new Ownership Interests are issued by the Borrower, all new, substituted, and additional Ownership Interests shall be issued to the Pledgor and, if a “certificated security” (as defined in Section 8-102 of the UCC as in effect in the State of New York), shall be promptly delivered to the Administrative Agent, together with undated stock powers endorsed in blank by the Pledgor with respect to any such Certificated Ownership Interests, and shall thereupon constitute Pledged Interests to be held by the Administrative Agent under the terms of this Agreement; and

(b) any subscriptions, warrants or any other rights or options shall be issued in connection with the Ownership Interests consisting of shares of Capital Stock, all new stock or other securities acquired through such subscriptions, warrants, rights or options by the Pledgor shall, if a “certificated security” (as defined in Section 8-102 of the UCC as in effect in the State of New York), be promptly delivered to the Administrative Agent, together with undated stock powers endorsed in blank, and shall thereupon constitute Pledged Interests to be held by the Administrative Agent under the terms of this Agreement.

- 2 -

4. Default. In the event of the occurrence of an Event of Default and so long as any such Event of Default is continuing, the Secured Parties may sell or otherwise dispose of the Pledged Interests at a public or private sale or make other commercially reasonable disposition of the Pledged Interests or any portion thereof after fifteen (15) days’ notice to the Pledgor and the Secured Parties, or any of them, may purchase the Pledged Interests or any portion thereof at any public sale. The proceeds of the public or private sale or other disposition shall be applied first to the costs of the Administrative Agent incurred in connection with the sale, expressly including, without limitation, any costs under Section 7 hereof, and then to the Guarantied Obligations as provided in the Loan Agreement. In the event the proceeds of the sale or other disposition of the Pledged Interests are insufficient to satisfy the Guarantied Obligations, the Pledgor shall remain liable for any such deficiency to the extent provided in the Guaranty. The Pledgor waives, to the extent permitted by Applicable Law, the rights of equity of redemption, appraisal, notice of acceptance, presentment, demand and marshalling, to the extent applicable.

5. Additional Rights of Secured Parties. In addition to its rights and privileges under this Agreement, the Secured Parties shall have all the rights, powers and privileges of a secured party under the UCC as in effect in any applicable jurisdiction and other Applicable Law.

6. Return of Pledged Interests to the Pledgor. Upon payment in full of all Obligations under the Loan Agreement and the other Loan Documents, and satisfaction in full of any other Guarantied Obligations, other than the Guarantied Obligations which survive the termination of the Loan Agreement as provided in Section 11.16 of the Loan Agreement, and after such time as the Lenders shall have no obligation to make any further Advances (including without limitation, with respect to Letters of Credit or draws thereon) to the Borrowers, or as otherwise set forth in the Loan Agreement (including, without limitation, in Section 5.11 thereof), this Agreement shall terminate and the Administrative Agent shall return the remaining Pledged Interests and all rights received by the Administrative Agent as a result of its possessory interest in the Pledged Interests to the Pledgor.

7. Disposition of Pledged Interests by Administrative Agent. The Pledged Interests are not registered or qualified under the various federal or state securities laws of the United States and disposition thereof after an Event of Default may be restricted to one or more private (instead of public) sales in view of the lack of such registration. The Pledgor understands that upon such disposition, the Secured Parties may approach only a restricted number of potential purchasers and further understands that a sale under such circumstances may yield a lower price for the Pledged Interests than if the Pledged Interests were registered and qualified pursuant to federal and state securities laws and sold on the open market. The Pledgor, therefore, agrees that:

(a) if the Secured Parties shall, pursuant to the terms of this Agreement, sell or cause the Pledged Interests or any portion thereof to be sold at a private sale, the Secured Parties shall have the right to rely upon the advice and opinion of any national brokerage or investment firm having recognized expertise and experience in connection with shares of communications tower companies (but shall not be obligated to seek such advice and the failure to do so shall not be considered in determining the commercial reasonableness of such action) as to the best manner in which to dispose of the Pledged Interests for sale and as to the best price reasonably obtainable at the private sale thereof; and

- 3 -

(b) that such reliance shall be conclusive evidence that the Secured Parties have handled such disposition in a commercially reasonable manner absent manifest error.

8. Pledgor’s Obligations Absolute. The obligations of the Pledgor under this Agreement shall be direct and immediate and not conditional or contingent upon the pursuit of any remedies against the Borrower or any other Person, nor against other security or liens available to any Secured Party. The Pledgor hereby waives any right to require that an action be brought against any other Person or to require that resort be had to any other security or to any balance of any deposit account or credit on the books of any of the Secured Parties in favor of any other Person prior to the exercise of remedies hereunder, or to require action hereunder prior to resort by the Administrative Agent to any other security or collateral for the Guarantied Obligations. No amendment, modification, waiver, transfer or renewal, extension, assignment or termination of this Agreement or of the Loan Agreement or of any other Loan Document, or of any instrument or document executed and delivered by the Pledgor or any other obligor with respect to the Guarantied Obligations to the Secured Parties, or any of them, nor additional advances made by the Secured Parties, or any of them, to the Borrower, nor the taking of further security, nor the retaking or re-delivery or release of the Collateral to the Borrower or any other Person or any other collateral or guaranty to the Borrower or any other Person by the Secured Parties, or any of them, nor any lack of validity or enforceability of any Loan Document or any term thereof, nor any other act of the Secured Parties, or any of them, shall release the Pledgor from any Guarantied Obligation, except a release or discharge executed in writing by the Administrative Agent in accordance with the Loan Agreement with respect to such Guarantied Obligation or upon full payment and satisfaction of all Guarantied Obligations. None of the Secured Parties shall, by any act, delay, omission or otherwise, be deemed to have waived any of its or their rights or remedies hereunder, unless such waiver is in writing and signed by the Administrative Agent in accordance with the Loan Agreement and then only to the extent therein set forth. A waiver by the Secured Parties, or any of them, of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion. Notwithstanding anything to the contrary contained herein, this Agreement shall terminate at such time as provided in Section 5.11 of the Loan Agreement.

9. Voting Rights.

(a) For so long as any Guarantied Obligations remain unpaid, after and during the continuation of an Event of Default, but subject to Section 15 hereof, (i) the Secured Parties may, upon fifteen (15) days’ prior written notice to the Pledgor of its intention to do so, exercise all voting rights, and all other ownership or consensual rights of the Pledged Interests , but under no circumstances are the Secured Parties or the Administrative Agent obligated by the terms of this Agreement to exercise such rights, and (ii) the Pledgor hereby appoints the Administrative Agent, which appointment shall be effective on the fifteenth (15th) day following the giving of notice by the Administrative Agent as provided in Section 9(a)(i) hereof, the Pledgor’s true and lawful attorney-in-fact and IRREVOCABLE PROXY to vote the Pledged Interests in any manner the Secured Parties deem advisable for or against all matters submitted or which may be submitted to a vote of shareholders, partners or members, as the case may be. The power-of-attorney granted hereby is coupled with an interest and shall be irrevocable.

- 4 -

(b) For so long as the Pledgor shall have the right to vote the Pledged Interests, the Pledgor covenants and agrees that it will not, without the prior written consent of the Administrative Agent, vote or take any consensual action with respect to the Pledged Interests which would constitute an Event of Default.

10. Amendments and Waivers. No amendment, modification, waiver, transfer or renewal, extension, assignment or termination of this Agreement or of the Loan Agreement or of any other Loan Document, or of any instrument or document executed and delivered by the Pledgor or any other obligor to the Secured Parties, or any of them, nor additional advances made by the Secured Parties, or any of them, to the Pledgor, nor the taking of further security, nor the retaking or re-delivery or release of the Collateral to the Pledgor or any other collateral or guaranty by the Secured Parties, or any of them, nor any lack of validity or enforceability of any Loan Document or any term thereof nor any other act of the Secured Parties, or any of them, shall release the Pledgor from any Guarantied Obligation, except a release or discharge executed in writing by the Administrative Agent in accordance with the Loan Agreement with respect to such Guarantied Obligation or upon full payment and satisfaction of all Guarantied Obligations and termination of the Commitments. None of the Secured Parties shall by any act, delay, omission or otherwise, be deemed to have waived any of its or their rights or remedies hereunder, unless such waiver is in writing and signed by the Administrative Agent or one or more of the Secured Parties in accordance with the Loan Agreement and then only to the extent therein set forth. A waiver by the Secured Parties, or any of them, of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion.

11. Assignment. The Pledgor hereby agrees that this Agreement or the rights hereunder may, in the discretion of the Secured Parties, or any of them, as applicable, be assigned by the Secured Parties, or any of them, in whole or in part in connection with any assignment of the Loan Agreement or the Obligations arising thereunder, as permitted thereunder. In the event this Agreement or the rights hereunder are so assigned by any of the Secured Parties, the terms “Administrative Agent” or “Secured Parties,” wherever used herein, shall be deemed, as applicable, to refer to and include any such assignee. This Agreement may not be assigned by the Pledgor, but shall apply to and bind the respective successors and permitted assigns of the Pledgor and inure to the benefit of the successors and permitted assigns of the Pledgor.

12. Notices. All notices and other communications required or permitted hereunder shall be in writing, and shall be given in the manner and at the addresses set forth in Section 11.1 of the Loan Agreement, and with respect to the Pledgor, at the address for the Borrower set forth in or otherwise provided pursuant to Section 11.1 of the Loan Agreement.

- 5 -

14. Severability. If any paragraph or part thereof shall for any reason be held or adjudged to be invalid, illegal or unenforceable by any court of competent jurisdiction, to the extent permitted by law, such paragraph or part thereof so adjudicated invalid, illegal or unenforceable shall be deemed separate, distinct and independent, and the remainder of this Agreement shall remain in full force and effect and shall not be affected by such holding or adjudication.

15. FCC Compliance. Notwithstanding anything herein which may be construed to the contrary, no action shall be taken by the Administrative Agent which may require the consent or approval of the FCC, and the proxy granted in Section 9(a) hereof shall not become effective, unless and until all requirements of the Communications Act, requiring the consent to or approval of such action by the FCC have been satisfied. The Pledgor covenants that, following and during the continuance of an Event of Default, upon request of the Administrative Agent, it will cause to be filed such applications and take such other action as may be reasonably requested by the Administrative Agent to obtain consent or approval of the FCC to any action contemplated by this Agreement and to give effect to the security interest of the Administrative Agent, including, without limitation, the execution of an application for consent by the FCC to an assignment or transfer involving a change in ownership or control pursuant to the provisions of the Communications Act.

16. Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed to be an original, but all such separate counterparts shall together constitute but one and the same instrument.

17. Jurisdiction and Venue. If any action or proceeding shall be brought by the Administrative Agent in order to enforce any right or remedy under this Agreement, the Pledgor hereby consents to the jurisdiction of any state or federal court of competent jurisdiction sitting within the area comprising the Southern District of New York on the date of this Agreement.

Nothing herein shall be construed to prohibit service of process by any other method permitted by law, or the bringing of any suit, action or proceeding in any other jurisdiction.

18. WAIVER OF JURY TRIAL. THE PLEDGOR WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY PROCEEDING ARISING OUT OF THIS AGREEMENT.

19. Administrative Agent. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the “Administrative Agent” shall be a reference to the Administrative Agent for the benefit of all of the Secured Parties, and each action taken or right exercised hereunder shall be deemed to have been so taken or exercised by the Administrative Agent for the benefit of and on behalf of all of the Secured Parties.

20. Further Assurances. The Pledgor hereby authorizes the Administrative Agent to file such financing statements and such other documents as the Administrative Agent may

- 6 -

reasonably require to protect or perfect the interest of the Secured Parties in the Pledged Interests, and the Pledgor further irrevocably appoints the Administrative Agent as its attorney-in-fact, with a power of attorney to execute on behalf of the Pledgor such UCC financing statement forms as the Administrative Agent may from time to time reasonably deem necessary or desirable to protect or perfect such interest in the Pledged Interests. Such power of attorney is coupled with an interest and shall be irrevocable. In addition, the Pledgor agrees to do, execute and deliver or cause to be done, executed and delivered all such further acts, documents and things as the Administrative Agent may reasonably require for the purpose of perfecting or protecting the rights of the Secured Parties hereunder or otherwise giving effect to this Agreement, all promptly upon request therefor.

WHEREAS, each Guarantor is a Restricted Subsidiary; and

WHEREAS, the Borrower and the Guarantors are mutually dependent on each other in the conduct of their respective businesses as an integrated operation, and the Borrower has as one of its corporate purposes the obtaining of financing needed from time to time, with the ability of the Borrower to obtain such financing being dependent, in part, on the successful operations of and the properties owned by each Guarantor; and

WHEREAS, each Guarantor has determined that its execution, delivery and performance of this Guaranty benefit, and are within the corporate purposes and in the best interests of, such Guarantor; and

WHEREAS, as a condition to the extension of the Loans by the Lenders and the issuance of Letters of Credit by the Issuing Bank, each Guarantor has agreed to execute this Guaranty, guaranteeing the payment by the Borrower of the Obligations under the Loan Agreement and the other Loan Documents; and

NOW, THEREFORE, in consideration of the above premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, subject to the provisions of Section 7 hereof, each Guarantor hereby agrees, for the benefit of the Guarantied Parties, as follows:

1. Payment. Each Guarantor hereby unconditionally guarantees, on a joint and several basis and subject to Section 7 hereof, to the Guarantied Parties full and prompt payment when due whether at maturity, by acceleration or otherwise of all Obligations under the Loan Agreement (collectively referred to herein as the “Guarantied Obligations”).

2. Obligations Joint and Several. Regardless of whether any proposed guarantor or any other Person or Persons is, are or shall become in any other way responsible to the Guarantied Parties, or any of them, for or in respect of the Guarantied Obligations or any part thereof, and regardless of whether or not any Person or Persons now or hereafter responsible to the Guarantied Parties, or any of them, for the Guarantied Obligations or any part thereof, whether under this Guaranty or otherwise, shall cease to be so liable, each Guarantor hereby declares and agrees that this Guaranty is and shall continue to be a joint and several obligation, shall be a continuing guaranty and shall be operative and binding.

3. Guaranty Final. Upon the execution and delivery of this Guaranty to the Administrative Agent by the Guarantors, this Guaranty shall be deemed to be finally executed and delivered by each Guarantor and shall not be subject to or affected by any promise or condition affecting or limiting any Guarantor’s liability (other than as expressly set forth in Section 7 hereof), and no statement, representation, agreement or promise on the part of the Guarantied Parties, the Borrower, or any of them, or any officer, employee or agent thereof, unless contained herein forms any part of this Guaranty or has induced the making hereof or shall be deemed in any way to affect the liability of any Guarantor hereunder.

4. Amendment and Waiver. No alteration or waiver of this Guaranty or of any of its terms, provisions or conditions shall be binding upon the Persons against whom enforcement is sought unless made in writing and signed by an authorized officer of such Person.

- 2 -

5. Dealings with Borrower. The Guarantied Parties, or any of them, may, from time to time, without exonerating or releasing any Guarantor in any way under this Guaranty, (i) take such further or other security or securities for the Guarantied Obligations or any part thereof as the Guarantied Parties, or any of them, may deem proper, consistent with the Loan Agreement, or (ii) release, discharge, abandon or otherwise deal with or fail to deal with any guarantor of the Guarantied Obligations or any security or securities therefor or any part thereof now or hereafter held by the Guarantied Parties, or any of them, or (iii) consistent with the Loan Agreement, amend, modify, extend, accelerate or waive in any manner any of the provisions, terms, or conditions of any of the Loan Documents, all as the Guarantied Parties, or any of them, may consider expedient or appropriate in their sole discretion. Without limiting the generality of the foregoing, or of Section 6 hereof, it is understood that the Guarantied Parties, or any of them, may, without exonerating or releasing any Guarantor, give up, or modify or abstain from perfecting or taking advantage of any security for the Guarantied Obligations and accept or make any compositions or arrangements, and realize upon any security for the Guarantied Obligations when, and in such manner, as the Guarantied Parties, or any of them, may deem expedient, consistent with the Loan Agreement, all without notice to any Guarantor, except as required by Applicable Law.

6. Guaranty Unconditional. Each Guarantor acknowledges and agrees that no change in the nature or terms of the Guarantied Obligations or any of the Loan Documents, or other agreements, instruments or contracts evidencing, related to or attendant with the Guarantied Obligations (including any novation), nor any determination of lack of enforceability thereof, shall discharge all or any part of the liabilities and obligations of any Guarantor pursuant to this Guaranty; it being the purpose and intent of each Guarantor and the Guarantied Parties that the covenants, agreements and all liabilities and obligations of each Guarantor hereunder are absolute, unconditional and irrevocable under any and all circumstances. Without limiting the generality of the foregoing, each Guarantor agrees that until each and every one of the covenants and agreements of this Guaranty is fully performed, no Guarantor’s undertakings hereunder shall be released, in whole or in part, by any action or thing which might, but for this Section of this Guaranty, be deemed a legal or equitable discharge of a surety or guarantor, or by reason of any waiver, omission of the Guarantied Parties, or any of them, or their failure to proceed promptly or otherwise, or by reason of any action taken or omitted by the Guarantied Parties, or any of them, whether or not such action or failure to act varies or increases the risk of, or affects the rights or remedies of, such Guarantor or by reason of any further dealings between the Borrower and the Guarantied Parties, or any of them, or any other guarantor or surety, and such Guarantor, to the extent permitted by Applicable Law, hereby expressly waives and surrenders any defense to its liability hereunder, or any right of counterclaim or offset of any nature or description which it may have or which may exist based upon, and shall be deemed to have consented to, any of the foregoing acts, omissions, things, agreements or waivers.

7. Maximum Guaranteed Amount. The creation or existence from time to time of Guarantied Obligations in excess of the amount committed to or outstanding on the date of this Guaranty is hereby authorized by each Guarantor, without notice to such Guarantor, and shall in no way impair or affect this Guaranty or the rights of the Guarantied Parties, or any of them, herein. Anything in this Guaranty to be contrary notwithstanding, it is the intention of each Guarantor and the Guarantied Parties, that such Guarantor’s obligations hereunder shall be, but not in excess of, the Maximum Guaranteed Amount. The “Maximum Guaranteed Amount” shall

- 3 -

mean for each Guarantor, calculated separately, the greater of (a) the amount of economic benefit received (directly or indirectly) by such Guarantor pursuant to the Loan Agreement and the other Loan Documents, and (b) the maximum amount which could be paid out by such Guarantor without rendering this Guaranty void or voidable under Applicable Law including, without limitation, (i) Title 11 of the United States Code, as amended, and (ii) applicable state law regarding fraudulent conveyances.

8. Bankruptcy. Upon the bankruptcy or winding up or other distribution of assets of the Borrower or any Guarantor or of any surety or guarantor for the Guarantied Obligations, the rights of the Guarantied Parties, or any of them, against any of the other Guarantors shall not be affected or impaired by the omission of the Guarantied Parties, or any of them, to prove its or their claim, as appropriate, and the Guarantied Parties may prove such claims as they see fit and may refrain from proving any claim and in their respective discretion they may value as they see fit or refrain from valuing any security held by the Guarantied Parties, or any of them, without in any way releasing, reducing or otherwise affecting the liability to the Guarantied Parties of each Guarantor.

9. Application of Payments. Any amount received by the Guarantied Parties, or any of them, from whatsoever source and applied toward the payment of the Guarantied Obligations shall be applied in such order of application as is set forth in the Loan Agreement.

10. Waivers by Guarantors. Each Guarantor hereby expressly waives, to the extent permitted by Applicable Law: (a) notice of acceptance of this Guaranty, (b) notice of the existence or creation of all or any of the Guarantied Obligations, (c) presentment, demand, notice of dishonor, protest, and all other notices whatsoever and (d) all diligence in collection or protection of or realization upon the Guarantied Obligations or any part thereof, any obligation hereunder, or any security for any of the foregoing. To the extent permitted by Applicable Law, all rights of subrogation, indemnification, contribution and reimbursement against the Borrower, all rights to enforce any remedy the Guarantied Parties, or any of them, may have against the Borrower and any benefit of, or right to participate in, any collateral or security now or hereinafter held by the Guarantied Parties, or any of them, in respect of the Guarantied Obligations, in each case, that each Guarantor may have at any time, are expressly subordinated to the prior payment, observance and performance in full of the Guarantied Obligations and each Guarantor shall withhold exercise of any such right or benefit until the Guarantied Obligations shall have been paid in full and all Commitments shall have been terminated. Any money received by any Guarantor in violation of the immediately preceding sentence shall be held in trust by such Guarantor for the benefit of the Guarantied Parties. If a claim is ever made upon the Guarantied Parties, or any of them, for the repayment or recovery of any amount or amounts received by any of them in payment of any of the Guarantied Obligations and such Person repays all or part of such amount by reason of (a) any judgment, decree, or order of any court or administrative body having jurisdiction over such Person or any of its property, or (b) any good faith settlement or compromise of any such claim effected by such Person with any such claimant, including the Borrower, then in such event each Guarantor agrees that any such judgment, decree, order, settlement, or compromise shall be binding upon such Guarantor, notwithstanding any revocation hereof or the cancellation of any promissory note or other instrument evidencing any of the Guarantied Obligations, and the Guarantors shall be and remain

- 4 -

obligated to such Person hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by such Person.

11. Assignment by the Guarantied Parties and the Guarantors. To the extent permitted under the Loan Agreement, the Guarantied Parties may each, and without notice of any kind, except as otherwise required by the Loan Agreement, sell, assign or transfer all or any of the Guarantied Obligations. No Guarantor shall assign its rights or obligations under this Guaranty without the consent of the Administrative Agent. In the event of an assignment permitted hereunder, each and every immediate and successive permitted assignee, transferee, or holder of all or any of the Guarantied Obligations, shall have the right to enforce this Guaranty, by suit or otherwise, for the benefit of such assignee, transferee or holder as fully as if such assignee, transferee or holder were herein by name specifically given such rights, powers and benefits. This Guaranty shall be binding upon each Guarantor, its successors and permitted assigns and inure to the benefit of such successors and assigns.

12. Remedies Cumulative. No delay by the Guarantied Parties, or any of them, in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise by the Guarantied Parties, or any of them, of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy. No action by the Guarantied Parties, or any of them, permitted hereunder shall in any way impair or affect this Guaranty. For the purpose of this Guaranty, the Guarantied Obligations shall include, without limitation, all Guarantied Obligations of the Borrower to the Guarantied Parties notwithstanding any right or power of any third party, individually or in the name of the Borrower or any other Person, to assert any claim or defense as to the invalidity or unenforceability of any such Guarantied Obligation, and no such claim or defense shall impair or affect the obligations of any Guarantor hereunder.

13. Miscellaneous. This is a Guaranty of payment and not of collection. In the event of a demand upon any Guarantor under this Guaranty, such Guarantor shall be held and bound to the Guarantied Parties directly as debtor in respect of the payment of the amounts hereby guaranteed. All reasonable costs and expenses, including attorneys’ fees and expenses, incurred by the Guarantied Parties, or any of them, in obtaining performance of or collecting payments due under this Guaranty shall be deemed part of the Guarantied Obligations guaranteed hereby. Any notice or demand which the Guarantied Parties, or any of them, may wish to give shall be served upon a Guarantor in the fashion prescribed for notices in Section 11.1 of the Loan Agreement in care of the Borrower at the address for the Borrower set forth in or otherwise provided pursuant to Section 11.1 of the Loan Agreement, and the notice so sent shall be deemed to be served as set forth in Section 11.1 of the Loan Agreement.

14. Visits and Inspections. Each Guarantor covenants and agrees that so long as any amount is owing on account of Guarantied Obligations or otherwise pursuant to this Guaranty, each Guarantor shall permit representatives of the Guarantied Parties, or any of them, to visit and inspect properties of such Guarantor during normal business hours after reasonable notice, inspect any of such Guarantor’s books and records and discuss with the principal officers of such Guarantor its businesses, assets, liabilities, financial positions, results of operations and business prospects.

- 5 -

15. Governing Law. This Guaranty shall be construed in accordance with and governed by the internal laws of the State of New York applicable to contracts made and to be performed in the State of New York.

Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned thereto in the Loan Agreement (as defined herein).

W I T N E S S E T H:

WHEREAS, SPECTRASITE COMMUNICATIONS, INC., a Delaware corporation (the “Borrower”), the Lenders (as defined therein), the Issuing Bank (as defined therein), the Syndication Agent (as defined therein) and the Administrative Agent (collectively with the Lenders, the Issuing Bank and the Syndication Agent, the “Secured Parties”), are all parties to that certain Loan Agreement dated as of                          , 2005 (as amended, modified, restated or supplemented from time to time, the “Loan Agreement”); and

WHEREAS, pursuant to the terms of the Loan Agreement, each Pledgor executed that certain Subsidiary Guaranty dated as of                          , 2005 (the “Guaranty”) and are required to execute and deliver this Agreement; and

WHEREAS, each Pledgor is a Restricted Subsidiary and is engaged in the business of owning, constructing, managing, operating and investing in communications tower facilities and/or related businesses as an integrated operation with the Borrower and its other Subsidiaries; and

WHEREAS, each Pledgor has determined that its execution, delivery and performance of this Agreement benefit, and are within the corporate purposes and in the best interests of such Pledgor; and

WHEREAS, each Pledgor and the Administrative Agent (on behalf of the Secured Parties) have agreed that the Ownership Interests owned by each Pledgor in each of the Subsidiaries of such Pledgor listed on Schedule 1 attached hereto shall be pledged by such Pledgor to the Secured Parties to secure the Guarantied Obligations (as defined in the Guaranty);

NOW, THEREFORE, in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Warranty. Each Pledgor hereby represents and warrants to the Secured Parties that (a) except for the security interest created hereby, such Pledgor owns the Pledged Interests (which constitute the percentage of the issued and outstanding Ownership Interests of the Subsidiaries as set forth on Schedule 1 attached hereto) free and clear of all Liens (except Permitted Liens), (b) the shares of Capital Stock pledged hereunder are duly issued, fully paid and non-assessable, and (c) such Pledgor has the unencumbered right to pledge the Pledged Interests. In addition, each Pledgor represents and covenants as follows: (1) the Pledged Interests represent (a) subject to Section 5.10 of the Loan Agreement, all of such Pledgor’s Ownership Interests in any direct Domestic Subsidiary of such Pledgor and (b) not less than sixty-five percent (65%) of the Ownership Interests in any direct wholly-owned Foreign Subsidiary of such Pledgor; and (2) upon possession and retention of the certificates evidencing Pledged Interests that are “securities” within the meaning of Article 8 of the Uniform Commercial Code (“UCC”) (such Pledged Interests hereinafter referred to as “Certificated Ownership Interests”) by the Administrative Agent, the Secured Parties shall have a valid and perfected first priority security interest in the Certificated Ownership Interests (other than Permitted Liens having priority) securing the payment of the Guarantied Obligations.

2. Security Interest. Each Pledgor hereby unconditionally grants and assigns to the Secured Parties, and their respective successors and permitted assigns, a continuing security interest in and security title to (a) the Ownership Interests set forth on Schedule 1 attached hereto, (b) subject to Section 5.10 of the Loan Agreement, the Ownership Interests in any Domestic Subsidiary of such Pledgor acquired by such Pledgor after the Agreement Date, and in each case, all certificates representing such Ownership Interests, all rights, options, warrants, stock or other securities or other property which may hereafter be received, receivable or distributed in respect of such Ownership Interests, together with all proceeds of the foregoing, including, without limitation, all dividends, cash, notes, securities or other property from time to time acquired, receivable or otherwise distributed in respect of, or in exchange for, the foregoing, all of which shall constitute “Pledged Interests” hereunder. Each Pledgor has delivered to the Administrative Agent all of its right, title and interest in and to the Pledged Interests, together

- 2 -

with certificates with respect to Certificated Ownership Interests, and undated stock powers endorsed in blank with respect to Certificated Ownership Interests, as security for the payment of all of the Guarantied Obligations of each Pledgor under this Agreement and the Guaranty and any extensions, renewals or amendments of any of the foregoing, however created, acquired, arising or evidenced, whether direct or indirect, absolute or contingent, now or hereafter existing, or due or to become due; it being the intention of the parties hereto that beneficial ownership of the Pledged Interests, including, without limitation, all voting, consensual and dividend rights, shall remain in such Pledgor until the occurrence and during the continuance of an Event of Default and until the Administrative Agent shall notify such Pledgor of the Administrative Agent’s exercise of voting and dividend rights to the Pledged Interests pursuant to Section 9 hereof.

3. Additional Ownership Interests. In the event that, during the term of this Agreement:

(a) any stock dividend, stock split, reclassification, readjustment, or other change is declared or made in the capital structure of any Subsidiary of any Pledgor, or any new Ownership Interests are issued by any Subsidiary of any Pledgor, or any new Subsidiary of any Pledgor is formed or acquired, all new, substituted, and additional Ownership Interests shall be issued to such Pledgor and shall be promptly delivered to the Administrative Agent, together with undated stock powers endorsed in blank by such Pledgor with respect to Certificated Ownership Interests, and shall thereupon constitute Pledged Interests to be held by the Administrative Agent under the terms of this Agreement; and

(b) any subscriptions, warrants or any other rights or options shall be issued in connection with the Ownership Interests consisting of shares of Capital Stock, all new stock or other securities acquired through such subscriptions, warrants, rights or options by each Pledgor shall be promptly delivered to the Administrative Agent, together with undated stock powers endorsed in blank, and shall thereupon constitute Pledged Interests to be held by the Administrative Agent under the terms of this Agreement.

Notwithstanding the foregoing, under this Section 3, no Pledgor shall be required to pledge or deliver Ownership Interests in any Subsidiary of such Pledgor if an express or deemed pledge of such Ownership Interests (including through pledges of Ownership Interests in Restricted Subsidiaries that are treated as flow-through or fiscally transparent entities for U.S. Federal income tax purposes) shall result in a Tax Impediment, as reasonably determined by the Borrower.

4. Default. In the event of the occurrence of an Event of Default and so long as any such Event of Default is continuing, the Secured Parties may sell or otherwise dispose of the Pledged Interests at a public or private sale or make other commercially reasonable disposition of the Pledged Interests or any portion thereof after fifteen (15) days’ notice to the applicable Pledgor and the Secured Parties, or any of them, may purchase the Pledged Interests or any portion thereof at any public sale. The proceeds of the public or private sale or other disposition shall be applied first to the costs of the Administrative Agent incurred in connection with the sale, expressly including, without limitation, any costs under Section 7 hereof, and then to the Guarantied Obligations as provided in the Loan Agreement. In the event the proceeds of the sale

- 3 -

or other disposition of the Pledged Interests are insufficient to satisfy the Guarantied Obligations, each Pledgor shall remain liable for any such deficiency to the extent provided in the Guaranty. Each Pledgor waives, to the extent permitted by Applicable Law, the rights of equity of redemption, appraisal, notice of acceptance, presentment, demand and marshalling, to the extent applicable.

5. Additional Rights of Secured Parties. In addition to its rights and privileges under this Agreement, the Secured Parties shall have all the rights, powers and privileges of a secured party under the UCC as in effect in any applicable jurisdiction and other Applicable Law.

6. Return of Pledged Interests to the Pledgor. Upon payment in full of all Obligations under the Loan Agreement and the other Loan Documents, and satisfaction in full of any other Guarantied Obligations, other than the Guarantied Obligations which survive the termination of the Loan Agreement as provided in Section 11.16 of the Loan Agreement, and after such time as the Lenders shall have no obligation to make any further Advances (including, without limitation, with respect to Letters of Credit or draws thereon) to the Borrower, or as otherwise set forth in the Loan Agreement (including, without limitation, Section 5.11 thereof), this Agreement shall terminate and the Administrative Agent shall return the remaining Pledged Interests and all rights received by the Administrative Agent as a result of its possessory interest in the Pledged Interests to the applicable Pledgor.

7. Disposition of Pledged Interests by Administrative Agent. The Pledged Interests are not registered or qualified under the various federal or state securities laws of the United States and disposition thereof after an Event of Default may be restricted to one or more private (instead of public) sales in view of the lack of such registration. Each Pledgor understands that upon such disposition, the Secured Parties may approach only a restricted number of potential purchasers and further understands that a sale under such circumstances may yield a lower price for the Pledged Interests than if the Pledged Interests were registered and qualified pursuant to federal and state securities laws and sold on the open market. Each Pledgor, therefore, agrees that:

(a) if the Secured Parties shall, pursuant to the terms of this Agreement, sell or cause the Pledged Interests or any portion thereof to be sold at a private sale, the Secured Parties shall have the right to rely upon the advice and opinion of any national brokerage or investment firm having recognized expertise and experience in connection with shares of communications tower companies (but shall not be obligated to seek such advice and the failure to do so shall not be considered in determining the commercial reasonableness of such action) as to the best manner in which to dispose of the Pledged Interests for sale and as to the best price reasonably obtainable at the private sale thereof; and

(b) that such reliance shall be conclusive evidence that the Secured Parties have handled such disposition in a commercially reasonable manner absent manifest error.

8. Pledgors’ Obligations Absolute. The obligations of each Pledgor under this Agreement shall be direct and immediate and not conditional or contingent upon the pursuit of any remedies against any of the Borrower or any other Person, nor against other security or liens available to any Secured Party. Each Pledgor hereby waives any right to require that an action

- 4 -

be brought against any other Person or to require that resort be had to any other security or to any balance of any deposit account or credit on the books of any of the Secured Parties in favor of any other Person prior to the exercise of remedies hereunder, or to require action hereunder prior to resort by the Administrative Agent to any other security or collateral for the Guarantied Obligations. No amendment, modification, waiver, transfer or renewal, extension, assignment or termination of this Agreement or of the Loan Agreement or of any other Loan Document, or of any instrument or document executed and delivered by any Pledgor or any other obligor with respect to the Guarantied Obligations to the Secured Parties, or any of them, nor additional advances made by the Secured Parties, or any of them, to the Borrower, nor the taking of further security, nor the retaking or re-delivery or release of the Collateral to the Borrower or any other Person or any other collateral or guaranty by the Secured Parties, or any of them, nor any lack of validity or enforceability of any Loan Document or any term thereof, nor any other act of the Secured Parties, or any of them, shall release any Pledgor from any Guarantied Obligation, except a release or discharge executed in writing by the Administrative Agent in accordance with the Loan Agreement with respect to such Guarantied Obligation or upon full payment and satisfaction of all Guarantied Obligations. None of the Secured Parties shall, by any act, delay, omission or otherwise, be deemed to have waived any of its or their rights or remedies hereunder, unless such waiver is in writing and signed by the Administrative Agent in accordance with the Loan Agreement and then only to the extent therein set forth. A waiver by the Secured Parties, or any of them, of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion. Notwithstanding anything to the contrary contained herein, this Agreement shall terminate at such time as provided in Section 5.11 of the Loan Agreement.

9. Voting Rights.

(a) For so long as any Guarantied Obligations remain unpaid, after and during the continuation of an Event of Default, but subject to the provisions of Section 15 hereof, (i) the Secured Parties or the Administrative Agent may, upon fifteen (15) days’ prior written notice to a Pledgor of its intention to do so, exercise all voting rights, and all other ownership or consensual rights of the Pledged Interests, but under no circumstances are the Secured Parties or the Administrative Agent obligated by the terms of this Agreement to exercise such rights, and (ii) each Pledgor hereby appoints the Administrative Agent, which appointment shall be effective on the fifteenth (15th) day following the giving of notice by the Administrative Agent as provided in Section 9(a)(i) hereof, such Pledgor’s true and lawful attorney-in-fact and IRREVOCABLE PROXY to vote the Pledged Interests in any manner the Secured Parties deem advisable for or against all matters submitted or which may be submitted to a vote of shareholders, partners or members, as the case may be. The power-of-attorney granted hereby is coupled with an interest and shall be irrevocable.

(b) For so long as a Pledgor shall have the right to vote the Pledged Interests, such Pledgor covenants and agrees that it will not, without the prior written consent of the Administrative Agent, vote or take any consensual action with respect to the Pledged Interests which would constitute an Event of Default.

- 5 -

10. Amendments and Waivers. No amendment, modification, waiver, transfer or renewal, extension, assignment or termination of this Agreement or of the Loan Agreement or of any other Loan Document, or of any instrument or document executed and delivered by any Pledgor or any other obligor to the Secured Parties, or any of them, nor additional advances made by the Secured Parties, or any of them, to any Pledgor, nor the taking of further security, nor the retaking or re-delivery or release of the Collateral to any Pledgor or any other collateral or guaranty by the Secured Parties, or any of them, nor any lack of validity or enforceability of any Loan Document or any term thereof nor any other act of the Secured Parties, or any of them, shall release any Pledgor from any Guarantied Obligation, except a release or discharge executed in writing by the Administrative Agent in accordance with the Loan Agreement with respect to such Guarantied Obligation or upon full payment and satisfaction of all Guarantied Obligations and termination of the Commitments. None of the Secured Parties shall by any act, delay, omission or otherwise, be deemed to have waived any of its or their rights or remedies hereunder, unless such waiver is in writing and signed by the Administrative Agent or one or more of the Secured Parties in accordance with the Loan Agreement and then only to the extent therein set forth. A waiver by the Secured Parties, or any of them, of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion.

11. Assignment. Each Pledgor hereby agrees that this Agreement or the rights hereunder may, in the discretion of the Secured Parties, or any of them, as applicable, be assigned by the Secured Parties, or any of them, in whole or in part in connection with any assignment of the Loan Agreement or the Obligations arising thereunder, as permitted thereunder. In the event this Agreement or the rights hereunder are so assigned by any of the Secured Parties, the terms “Administrative Agent” or “Secured Parties,” wherever used herein, shall be deemed, as applicable, to refer to and include any such assignee. This Agreement may not be assigned by any Pledgor, but shall apply to and bind the respective successors and permitted assigns of such Pledgor and inure to the benefit of the successors and permitted assigns of such Pledgor.

12. Notices. All notices and other communications required or permitted hereunder shall be in writing, and shall be given in the manner and at the addresses set forth in Section 11.1 of the Loan Agreement, and with respect to each Pledgor, at the address for the Borrower set forth in or otherwise provided pursuant to Section 11.1 of the Loan Agreement.

13. Governing Law; Entire Agreement. The provisions of this Agreement shall be construed and interpreted, and all rights and obligations of the parties hereto determined, in accordance with the internal laws of the State of New York applicable to contracts made and to be performed in the State of New York. This Agreement, together with all documents referred to herein, constitutes the entire agreement between the parties with respect to the matters addressed herein and may not be modified except by a writing executed by the Administrative Agent and the Pledgors and delivered by the Administrative Agent to the Pledgors.

14. Severability. If any paragraph or part thereof shall for any reason be held or adjudged to be invalid, illegal or unenforceable by any court of competent jurisdiction, to the extent permitted by law, such paragraph or part thereof so adjudicated invalid, illegal or unenforceable shall be deemed separate, distinct and independent, and the remainder of this

- 6 -

Agreement shall remain in full force and effect and shall not be affected by such holding or adjudication.

15. FCC Compliance. Notwithstanding anything herein which may be construed to the contrary, no action shall be taken by the Administrative Agent which may require the consent or approval of the FCC, and the proxy granted in Section 9(a) hereof shall not become effective, unless and until all requirements of the Communications Act requiring the consent to or approval of such action by the FCC have been satisfied. Each Pledgor covenants that, following and during the continuance of an Event of Default, upon request of the Administrative Agent, it will cause to be filed such applications and take such other action as may be reasonably requested by the Administrative Agent to obtain consent or approval of the FCC to any action contemplated by this Agreement and to give effect to the security interest of the Administrative Agent, including, without limitation, the execution of an application for consent by the FCC to an assignment or transfer involving a change in ownership or control pursuant to the provisions of the Communications Act.

16. Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed to be an original, but all such separate counterparts shall together constitute but one and the same instrument.

17. Administrative Agent. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the “Administrative Agent” shall be a reference to the Administrative Agent for the benefit of all of the Secured Parties, and each action taken or right exercised hereunder shall be deemed to have been so taken or exercised by the Administrative Agent for the benefit of and on behalf of all of the Secured Parties.

18. Jurisdiction and Venue. If any action or proceeding shall be brought by the Administrative Agent in order to enforce any right or remedy under this Agreement, each Pledgor hereby consents to the jurisdiction of any state or federal court of competent jurisdiction sitting within the area comprising the Southern District of New York on the date of this Agreement. Each Pledgor hereby agrees, to the extent permitted by Applicable Law that service of the summons and complaint and all other process which may be served in any such suit, action or proceeding may be effected by mailing by registered mail a copy of such process to the offices of such Pledgor, at the address for the Borrower, as set forth in or otherwise provided pursuant to Section 11.1 of the Loan Agreement, and that personal service of process shall not be required. Nothing herein shall be construed to prohibit service of process by any other method permitted by law, or the bringing of any suit, action or proceeding in any other jurisdiction.

19. Waiver of Jury Trial. EACH PLEDGOR WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY PROCEEDING ARISING OUT OF THIS AGREEMENT.

20. Joinder of Subsidiaries. From time to time additional Subsidiaries of the Borrower may be joined as Pledgors under this Agreement by executing a Form of Joinder, substantially in the form of Exhibit A attached hereto, and any such other documentation as reasonably requested by the Administrative Agent.

Each Subsidiary shall take or cause to be taken such acts and actions as shall be necessary or appropriate to assure that the Security Interest in such Subsidiary’s Collateral shall not become subordinate or junior to the security interests, liens or claims of any other Person, and that such Subsidiary’s Collateral shall not otherwise be or become subject to any Lien, except for Permitted Liens.

Each Subsidiary further agrees that it shall promptly advise the Administrative Agent, in writing making reference to this Section 5 of this Agreement, of the opening of any material new place of business for such Subsidiary, the closing of any existing material place of business for such Subsidiary, or any change in the location of the place where it keeps the Collateral or of its chief executive office.

6. Collateral Not Fixtures. The parties intend that, to the extent permitted by Applicable Law, the Collateral, including, without limitation, all communications towers, shall remain personal property irrespective of the manner of its attachment or affixation to realty.

7. Covenants Regarding Collateral. Any and all injury to, or loss or destruction of, the Collateral shall be at each Subsidiary’s risk, and shall not release such Subsidiary from its obligations hereunder. Each Subsidiary agrees not to sell, transfer, assign, dispose of, mortgage, grant a security interest in, or encumber any of the Collateral except as permitted under the Loan Agreement. Each Subsidiary agrees to maintain in force such insurance with respect to the Collateral as is required under the Loan Agreement. Each Subsidiary agrees to pay all required taxes, liens, and assessments upon the Collateral, its use or operation, as required under the Loan Agreement. Each Subsidiary further agrees that the Administrative Agent may, but shall in no event be obligated to, following written notice to such Subsidiary, insure any of the Collateral in such form and amount as the Administrative Agent may deem necessary or desirable if such Subsidiary fails to obtain insurance as required by the Loan Agreement, and that the Administrative Agent may pay or discharge any taxes if such Subsidiary fails to pay such taxes as required by the Loan Agreement or Liens (which are not Permitted Liens) on any of the Collateral, and such Subsidiary agrees to pay any such sum so expended by the Administrative Agent, with interest at the Default Rate, and such amounts shall be deemed to be a part of the Guarantied Obligations secured by the Collateral under the terms of this Agreement.

8. Covenants Regarding Contracts, Other Contracts and Leases. Except where the failure to do so would not reasonably be expected to cause a Materially Adverse Effect to the Borrower and the Restricted Subsidiaries taken as a whole, each Subsidiary shall fulfill, perform and observe each and every material condition and covenant of such Subsidiary contained in any of the material Contracts, the Other Contracts or the Leases, other than those being contested in good faith or unless the other party thereto is in default. The rights and interests granted to the Administrative Agent hereunder include all of each Subsidiary’s rights and title (i) to modify the

-6-

Contracts, the Other Contracts and the Leases, (ii) to terminate the Contracts, the Other Contracts and the Leases, and (iii) to waive or release the performance or observance of any obligation or condition of the Contracts, the Other Contracts and the Leases; provided, however, that each Subsidiary shall have the right to exercise these rights in a fashion consistent with this Agreement prior to any Event of Default and at any time that an Event of Default is not continuing and that these rights shall not be exercised by the Administrative Agent prior to the occurrence and during the continuation of an Event of Default.

9. Remedies. Upon the occurrence and during the continuation of an Event of Default, the Secured Parties shall have such rights and remedies as are set forth in the Loan Agreement, the other Loan Documents and herein, all the rights, powers and privileges of a secured party under the UCC of the State of New York and any other applicable jurisdiction, and all other rights and remedies available to the Secured Parties, or any of them, at law or in equity. Each Subsidiary covenants and agrees that any notification of intended disposition of any Collateral, if such notice is required by law, shall be deemed reasonably and properly given if given in the manner provided for in Section 19 hereof at least ten (10) days prior to such disposition. Under such circumstances, the Secured Parties shall have the right to request the appointment of a receiver for the properties and assets of each Subsidiary, and each Subsidiary hereby consents to such right and to such appointment and hereby waives any objection it may have thereto and hereby waives the right to have a bond or other security posted by the Administrative Agent or any other Person in connection therewith. Each Subsidiary agrees, after the occurrence of an Event of Default and during the continuation of an Event of Default, to take any actions that the Secured Parties may reasonably request in order to enable the Administrative Agent to obtain and enjoy the full rights and benefits granted to the Administrative Agent under this Agreement and the other Loan Documents. Without limiting the generality of the foregoing, each Subsidiary shall, at such Subsidiary’s cost and expense, use its reasonable best efforts to assist in obtaining all approvals of the FCC which are then required by law for or in connection with any action or transaction contemplated by this Agreement or Article 9 of the UCC as in effect in any applicable jurisdiction, and, at the Administrative Agent’s request, prepare, sign and file with the FCC the assignor’s or transferor’s portion of any application or applications for consent to the assignment of the Licenses or transfer of control thereof necessary or appropriate under the FCC’s rules for approval of any sale or transfer of the Licenses in connection with the Administrative Agent’s exercise of remedies under this Agreement. The Administrative Agent shall have the right, in connection with the issuance of any order for relief in a bankruptcy proceeding, to petition the bankruptcy court for the transfer of control or assignment of the Collateral to a receiver, trustee, transferee, or similar official or to any purchaser of the Collateral pursuant to any public or private sale, foreclosure or other exercise of remedies available to the Administrative Agent, all as permitted by Applicable Law. All amounts realized or collected through the exercise of remedies hereunder shall be applied to the Guarantied Obligations as provided in the Loan Agreement.

10. Notification of Account Debtors. Upon the occurrence and during the continuation of an Event of Default, the Administrative Agent may notify the account debtors that all payments with respect to Accounts of any Subsidiary are to be paid directly to the Administrative Agent and any amount thereafter paid to such Subsidiary shall be received in trust by such Subsidiary for the benefit of the Administrative Agent and segregated from other

-7-

funds of such Subsidiary and paid over to the Administrative Agent in the form received (together with any necessary endorsements).

11. Remedies of Administrative Agent. Upon the occurrence of an Event of Default and during the continuation thereof, and after written notice to a Subsidiary, the Administrative Agent or its designee may proceed to perform any and all of the obligations of such Subsidiary contained in any of the Contracts, Other Contracts or Leases and exercise any and all rights of such Subsidiary therein contained as fully as such Subsidiary itself could. Each Subsidiary hereby appoints the Administrative Agent its attorney-in-fact, with power of substitution, to take such action, execute such documents, and perform such work after the occurrence and during the continuation of an Event of Default as the Administrative Agent may deem appropriate in exercise of the rights and remedies granted the Secured Parties, or any of them, herein or in any other Loan Document following written notice to such Subsidiary. The powers herein granted shall include, without limitation, powers to: (a) xxx on the Contracts, the Other Contracts or the Leases; (b) seek all governmental approvals (other than FCC approvals) required for the operation of the business of each Subsidiary; (c) modify or terminate the Contracts, the Other Contracts and the Leases; and (d) waive or release the performance or observance of any obligation under any of the Contracts, Other Contracts or Leases. The power of attorney granted herein is coupled with an interest and shall be irrevocable.

12. Additional Remedies. Upon the occurrence of an Event of Default and during the continuation thereof, should any Subsidiary fail to perform or observe any covenant or comply with any condition contained in any of the Contracts, the Other Contracts or the Leases, then following written notice to such Subsidiary, the Administrative Agent may, but without obligation to do so and without releasing any such Subsidiary from its obligation to do so, and after written notice to such Subsidiary, perform such covenant or condition and, to the extent that the Administrative Agent shall incur any reasonable costs or pay any expenses in connection therewith, including, without limitation, any reasonable costs or expenses of litigation associated therewith, such costs, expenses or payments shall be included in the Guarantied Obligations secured hereby and shall bear interest from the payment of such costs or expenses by the Administrative Agent at the Default Rate. None of the Secured Parties shall be obliged to perform or discharge any obligation of any Subsidiary under any of the Contracts, the Other Contracts or the Leases, and, except as may result from the bad faith, gross negligence or willful misconduct of the Person seeking indemnification, each Subsidiary agrees to indemnify and hold each Secured Party harmless against any and all liability, loss or damage which any such Person may incur under any of the Contracts, the Other Contracts or the Leases or under or by reason of this Agreement, and any and all claims and demands whatsoever which may be asserted against any Subsidiary by reason of an act of any Secured Party under any of the terms of this Agreement or under the Contracts, the Other Contracts or the Leases.

13. Administrative Agent May Collect Accounts. Each Subsidiary hereby further appoints the Administrative Agent as its attorney-in-fact, with power of substitution, with authority to collect all Accounts, to endorse the name of such Subsidiary on any note, acceptance, check, draft, money order or other evidence of debt or of payment which constitutes a portion of the Collateral and which may come into the possession of the Secured Parties, or any of them, and generally to do such other things and acts in the name of such Subsidiary with respect to the Collateral as are necessary or appropriate to protect or enforce the rights hereunder

-8-

of the Secured Parties after the occurrence and during the continuation of an Event of Default. Each Subsidiary further authorizes the Administrative Agent, effective upon the occurrence of an Event of Default and during the continuation thereof, to compromise and settle or to sell, assign or transfer or to ask, collect, receive or issue any and all claims possessed by such Subsidiary which constitute a portion of the Collateral, all in the name of such Subsidiary. After deducting all reasonable expenses and charges (including, without limitation, the Administrative Agent’s attorneys’ fees) of retaking, keeping, storing and selling the Collateral, the Administrative Agent may apply the proceeds in payment of any of the Guarantied Obligations in the order of application set forth in the Loan Agreement. The power of attorney granted herein is coupled with an interest and shall be irrevocable. Each Subsidiary agrees that if steps are taken by the Administrative Agent to enforce its rights hereunder, or to realize upon any of the Collateral, such Subsidiary shall pay to the Administrative Agent the amount of the Administrative Agent’s reasonable costs, including, without limitation, attorneys’ fees, and such Subsidiary’s obligation to pay such amounts shall be deemed to be a part of the Guarantied Obligations secured hereunder. Upon the occurrence and during the continuation of an Event of Default, each Subsidiary shall segregate all proceeds of any Collateral from the other assets of such Subsidiary.

14. Indemnification. Each Subsidiary shall indemnify and hold harmless each Secured Party and any other Person acting hereunder for all losses, costs, damages, fees and expenses whatsoever associated with the exercise of the powers of attorney granted herein and shall release each Secured Party and any other Person acting hereunder from all liability whatsoever for the exercise of the foregoing powers of attorney and all actions taken pursuant thereto, except, in either event, in the case of bad faith, gross negligence or willful misconduct by the Person seeking indemnification.

15. Remedies Cumulative. Each Subsidiary agrees that the rights of the Secured Parties, or any of them, under this Agreement, the Loan Agreement, any other Loan Document, or any other contract or agreement now or hereafter in existence among the Secured Parties and the Subsidiaries and the other obligors thereunder, or any of them, shall be cumulative, and that each Secured Party may from time to time exercise such rights and such remedies as such Person or Persons may have thereunder and under the laws of the United States or any state, as applicable, in the manner and at the time that such Person or Persons in its or their sole discretion desire, subject to the terms of such agreements. Each Subsidiary further expressly agrees that the Secured Parties shall in no event be under any obligation to resort to any Collateral secured hereby prior to exercising any other rights that the Secured Parties, or any of them, may have against such Subsidiary or its property, nor shall the Secured Parties be obliged to resort to any other collateral or security for the Guarantied Obligations, other than the Collateral, prior to any exercise of the Administrative Agent’s rights against such Subsidiary and its property hereunder.

16. Obligations Commercial in Nature. Each Subsidiary hereby acknowledges that the Guarantied Obligations arose out of a commercial transaction, and agrees that if an Event of Default shall occur and be continuing, the Administrative Agent shall, to the extent permitted by Applicable Law, have the right to immediate possession without notice or a hearing, and hereby knowingly and intelligently waives, to the extent permitted by Applicable Law, any and all rights it may have to any notice and posting of a bond by the Secured Parties, or any of them, prior to seizure by the Administrative Agent or any of its transferees, assigns or successors in interest of the Collateral or any portion thereof.

-9-

17. Amendments and Waivers. No amendment, modification, waiver, transfer or renewal, extension, assignment or termination of this Agreement or of the Loan Agreement or of any other Loan Document, or of any instrument or document executed and delivered by any Subsidiary or any other obligor to the Secured Parties, or any of them, nor additional advances made by the Secured Parties, or any of them, to the Borrower, nor the taking of further security, nor the retaking or re-delivery or release of the Collateral to any Subsidiary by the Secured Parties, or any of them, nor any lack of validity or enforceability of any Loan Document or any term thereof, nor any other act of the Secured Parties, or any of them, shall release any Subsidiary from any Guarantied Obligation, except a release or discharge executed in writing by the Administrative Agent in accordance with the Loan Agreement with respect to such Guarantied Obligation or upon full payment and satisfaction of all Guarantied Obligations and termination of the Commitments. None of the Secured Parties shall by any act, delay, omission or otherwise, be deemed to have waived any of its or their rights or remedies hereunder, unless such waiver is in writing and signed by the Administrative Agent in accordance with the Loan Agreement and then only to the extent therein set forth. A waiver by the Secured Parties, or any of them, of any right or remedy on any occasion shall not be construed as a bar to the exercise of any such right or remedy which any such Person would otherwise have had on any other occasion. Notwithstanding anything to the contrary contained herein, this Agreement shall terminate at such time as provided in Section 5.11 of the Loan Agreement.

18. Assignment. Each Subsidiary agrees that this Agreement or the rights hereunder may, in the discretion of the Secured Parties, or any of them, as applicable, be assigned by the Secured Parties, or any of them, in whole or in part in connection with any assignment of the Loan Agreement or the Obligations arising thereunder, as permitted thereunder. In the event this Agreement or the rights hereunder are so assigned by any of the Secured Parties, the terms “Secured Parties” or “Administrative Agent” wherever used herein shall be deemed, as applicable, to refer to and include any such assignee.

21. Severability. If any paragraph or part thereof of this Agreement shall for any reason be held or adjudged to be invalid, illegal or unenforceable by any court of competent

-10-

jurisdiction, to the extent permitted by law, such paragraph or part thereof so adjudicated invalid, illegal or unenforceable shall be deemed separate, distinct and independent, and the remainder of this Agreement shall remain in full force and effect and shall not be affected by such holding or adjudication.

22. FCC Compliance. Notwithstanding anything herein which may be construed to the contrary, no action shall be taken by the Administrative Agent which may require the consent or approval of the FCC, unless and until all requirements of Applicable Law, including, without limitation any required approval under the Communications Act, requiring the consent to or approval of such action by the FCC or any governmental or other authority have been satisfied. Each Subsidiary covenants that, following and during the continuation of an Event of Default, upon request of the Administrative Agent, it will cause to be filed such applications and take such other action as may be reasonably requested by the Administrative Agent to obtain consent or approval of the FCC to any action contemplated by this Agreement and to give effect to the Security Interest of the Administrative Agent, including, without limitation, the execution of an application for consent by the FCC to an assignment or transfer involving a change in ownership or control pursuant to the provisions of the Communications Act.

23. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such separate counterparts shall together constitute but one and the same instrument.

24. Changes in Applicable Law. The parties acknowledge their intent that, upon the occurrence of an Event of Default and during the continuation thereof, the Administrative Agent shall receive, to the fullest extent permitted by Applicable Law and governmental policy (including, without limitation, the rules, regulations and policies of the FCC), all rights necessary or desirable to obtain, use or sell the Collateral and to exercise all remedies available to it under this Agreement, the UCC as in effect in any applicable jurisdiction, or other Applicable Law. The parties further acknowledge and agree that, in the event of changes in law or governmental policy occurring subsequent to the date hereof that affect in any manner the Administrative Agent’s rights of access to, or use or sale of, the Collateral, or the procedures necessary to enable the Administrative Agent to obtain such rights of access, use or sale, the Administrative Agent and each Subsidiary shall amend this Agreement in such manner as the Administrative Agent shall reasonably request in order to provide the Administrative Agent such rights to the greatest extent possible consistent with Applicable Law and governmental policy.

25. Administrative Agent. Each reference herein to any right granted to, benefit conferred upon or power exercisable by the “Administrative Agent” shall be a reference to the Administrative Agent for the benefit of all the Secured Parties, and each action taken or right exercised hereunder shall be deemed to have been so taken or exercised by the Administrative Agent for the benefit of and on behalf of all the Secured Parties.

26. Jurisdiction and Venue. If any action or proceeding shall be brought by the Administrative Agent in order to enforce any right or remedy under this Agreement, each Subsidiary hereby consents to the jurisdiction of any state or federal court of competent jurisdiction sitting within the area comprising the Southern District of New York on the date of this Agreement.

The Assignor has not acted and will not be acting as either the representative, agent or trustee of the Assignee with respect to matters arising out of or relating to the Loan Agreement or this Agreement. From and after the Effective Date, the Assignor shall have no rights or obligations with respect to the Assigned Loans and the Assigned Commitments.
